The Holter Mindset. Applied to Breathing.

For decades, lung function has been measured in controlled laboratory environments short snapshots that rarely reflect how we actually breathe in daily life.

Wearables transformed cardiovascular monitoring.

Respiratory monitoring remained behind.
Until now.

Breathing isn’t static.

Why measure it that way?

By embedding advanced respiratory sensors into a soft, lightweight T-shirt, ANASA® delivers continuous assessment of lung function in real time.

Respiratory rate,
Amplitude,
Ventilation timing,
Respiratory variability,
Respiratory symmetry
Thoracoabdominal synergy and asynchrony,
Comprehensive Breathing Quality Index.

All captured continuously. All outside controlled environments.

ANASA introduces contextual journaling as part of its respiratory intelligence system.

Through structured activity logging and precise time-stamping, respiratory signals can be aligned with real-life events whether a participant is eating, speaking, sleeping, or exercising. This allows breathing patterns to be tracked, correlated, and analyzed within their true daily context.

The result is more than continuous data collection.
It is respiratory insight anchored in time and behavior.

Not just measurements.
But a clearer understanding of how the body breathes, responds, and adapts throughout everyday life.

General Information

Q: What is the ANASA® Smart Breathing Shirt? A: The ANASA® Smart Breathing Shirt (also referred to as the ANASA® System) is a wearable designed to capture respiratory data from the thoracic and abdominal areas. It consists of two main components: an Electronic Device (also referred to as the ANASA® Reader) and a Sensor-embedded Shirt (also referred to as the ANASA® Shirt). The ANASA® Reader continuously measures respiratory motion through inductive sensors integrated into the ANASA® Shirt, recording and storing data internally and transmitting for visualization and analysis. The Shirt’s seamless, elastic textile incorporates two embedded inductive sensing zones positioned around the chest and abdomen, ensuring both measurement accuracy and wearer comfort during daily activities. Powered by ATRIDE’s advanced low-power sensing technology, the ANASA® Smart Breathing Shirt enables continuous, non-intrusive monitoring of breathing frequency, posture, and movement. Designed for adults aged 18 years and above, it combines precise respiratory measurement with a lightweight and discreet form factor suitable for long-term wellness and research use. Q: Is ANASA® a medical device? A: No. It is not a medical device and does not diagnose, treat, or provide therapy. It is intended for long-term logging of respiratory performance for research, wellness, or remote monitoring purposes. Q: Who can use ANASA®? A: Lay Users aged 18 and above. It can be used by individuals interested in tracking respiratory patterns, or by professional users, including healthcare and research personnel as part of studies with human subjects. Q: Can I use ANASA® if I have a pacemaker? A: No. People with pacemakers should not wear the ANASA® Smart Breathing Shirt.

Before Use

Q: What should I do before my first use? A: Fully charge the ANASA® Reader (approx. 4 hours), ensure the shirt is clean and dry, and follow all safety precautions in the manual. Q: How do I know my ANASA® package is complete? A: It should include the ANASA® Shirt, the ANASA® Reader, a USB-C charging cable, a dedicated washing bag, and the user manual. If anything is missing or damaged, contact ATRIDE. Q: How do I choose the right ANASA® size? A: For the best performance, ANASA® should fit snugly against the body. The fabric is elastic, so it stays comfortable while ensuring accurate measurements. Use the size chart below to find the most suitable fit for each person. Thorax & Abdominal expansion. S 70-81 cm M 80x93 cm L 91-106 cm XL 104-121 cm It is critical to take measurements to ensure a snug fit. ⚠️Warning: If the shirt is loose, the sensors will degrade signal quality. If a participant falls between sizes (e.g., could be M or L), prioritize the snugger fit (M) to ensure data integrity. Q: Are there people who should not wear ANASA®? A: Yes, users allergic to Lyocell and /or modal or those with open wounds, skin irritation, or pacemakers. Q: What should I do before starting a session of lab measurements? A: To ensure data integrity, adopt the following "Basics" before every use: Charge: Keep the device charged at all times. If left uncharged overnight with Bluetooth on, the battery may deplete before recording begins. Visual Confirmation: Before starting, verify the Red light is blinking on the side of the Reader. This is the only definitive proof that data is logging. Reset: If necessary, you can restart the device by pressing the small physical button (front side, next to the charging port) to ensure it initializes correctly and the red light starts blinking.

Configuration & Synchronisation

Q: Is the ANASA® system accompanied by software? A: The ANASA® system is not accompanied by a lay user-facing mobile application intended for everyday consumer use. Instead, ATRIDE provides a suite of software tools designed for advanced users, such as researchers, clinicians, engineers, and technology partners, who require flexibility, control, and transparency over data acquisition and processing. These tools support efficient workflows across the full data lifecycle, including: Device communication and data acquisition: Software utility for wired data transfer and time synchronization, with TTL support where necessary. Fleet management: The ANASA® Fleet Manager software can manage multiple ANASA® devices, including time synchronization, data download, and firmware updates [Download link]. Real-time and near-real-time data handling: Capabilities for visualization and processing of incoming signals, including support for multi-device setups (e.g. multiple shirts producing synchronized data streams). Basic and exploratory visualizations: Software components that allow users to inspect raw and preprocessed respiratory and motion signals for quality control and exploratory analysis. Signal processing and feature extraction: ATRIDE provides code snippets that enable advanced users to extract features from entire recorded signals or segmented signal windows. Please contact the ATRIDE team for more information and access to the tools. Q: How can I set the device clock to local time? A: The ANASA® Reader includes an internal real-time clock (RTC) for time-stamping data. To ensure high precision (

Data Access & Synchronization

Q: How do I manage multiple shirts at the same time? A: To handle multiple devices efficiently, use the ANASA® Fleet Manager software. This tool allows you to synchronize clocks, download data, and update firmware for an entire fleet of devices simultaneously. Prerequisites: Ensure you have Python and pip installed on your computer before starting. Installation: Locate the anasa_fleet_manager.py file and run it via your terminal using the command: python anasa_fleet_manager.py or python3 anasa_fleet_manager.py. The application will automatically install necessary drivers upon the first run. Synchronizing Clocks: Connect your devices via USB. Click "SYNCHRONIZE ALL CLOCKS" to automatically process every connected device one by one. This ensures all devices match your computer's time (use the "Hr Offset" box if a different time zone is required). Downloading Data: Click "DOWNLOAD DATA FROM ALL DEVICES". The system creates an Anasa_Data folder and organizes files by device ID. It includes a smart "Resume Feature" that skips files already downloaded to save time. Firmware Updates: If you have a new .UF2 update file, select it and click "FLASH ALL DETECTED DEVICES" to update and restart the entire fleet automatically. Q: How can I synchronize ANASA® data with other research devices? A: Synchronization depends on whether you use a wired or wireless setup with your other devices (e.g., EDA, PPG, MoCap). If you use a wired connection (recommended for highest accuracy), you can connect the ANASA® Reader directly to your computer using a long USB cable to a COM (serial) port. This allows you to stream data in real time from all devices into a single CSV file, sharing the same computer clock. The SD card in the Reader continues to log as a backup. The ANASA® Reader supports the following serial commands: streamdata — starts streaming both respiratory channels (L1 and L2) stopstream — stops streaming streamreg 0x02 — streams only the abdomen (L2) channel stream reg0x00 — streams only the chest (L1) channel If you use a wireless connection, synchronization depends on aligning the internal clocks of your devices before the session begins. Prior to data collection, use the ANASA® Fleet Manager to "Sync Selected Device," which calibrates the ANASA® internal clock to your computer’s time with fewer than 4ms precision. After the session, simply download the files using the ANASA® Fleet Manager, and the timestamps in the resulting CSV files will correspond accurately with your external devices. The ANASA® System can also support TTL synchronization signals for advanced setups, such as motion capture systems. If you wish to explore this option, please contact the ATRIDE hardware team for assistance.

During Use

Q: How does the ANASA® Reader start? A: The ANASA® Reader turns on automatically when attached to the ANASA® Shirt via the snap-button connectors and worn. It switches off when removed. Q: What do the LED Status Indicator lights mean? Α: The ANASA® Reader features two LED indicators: a main LED on the top and a secondary LED on the side near the USB-C port. Each provides information about the device’s current status: Main LED (Top): 🔴 Red ON – Audio recording in progress 🟢 Pulsing Green – Charging 🟢 Green ON – Fully charged 🟠 Orange ON – Low battery (approx. 10% remaining, recharge soon) Side LED (Next to USB Port): 🔴 Blinking Red – Data logging 🔵 Blue ON / OFF – Bluetooth enabled / disabled Q: Can I wear it under normal clothes? A: Yes. It should be worn snugly, like an undershirt. Avoid thick outer layers that restrict movement. Q: Can I use it while sleeping or exercising? A: Yes, for normal daily activities. Avoid swimming, showering, or heavy sweating. Q: How do I record a voice note? A: Press and hold the main button to record up to one minute of audio. The Main LED Status Indicator turns red during recording. Q: Can I view my data on my phone or through an app? A: Not currently. The ANASA® system stores data locally on the ANASA® Reader’s microSD card. However, advanced users can export their data and communicate with the ANASA® Reader by connecting the electronic device to a computer and using the ANASA® Fleet Manager software.

Charging & Battery

Q: How do I charge the ANASA® Reader? A: Connect it via USB-C to a computer or low-power 5 V charger (max 100 mA). Charging takes ~4 hours. Q: What is the expected battery life? A: When fully charged, the ANASA® Reader provides operation for up to 3 days under normal use. We recommend charging the Reader overnight (similar to a mobile phone), as battery life varies based on features used (e.g., usage intensity, Bluetooth activity, and microphone usage frequency). Q: Can I use ANASA® while charging? A: No. For safety, the ANASA® Reader automatically disables operation during charging. Q: What if the Main LED Status Indicator doesn’t light up during charging? A: Ensure the USB-C cable is correctly inserted and use a verified power source. If still off, contact support.

Maintenance & Cleaning

Q: How should I clean the ANASA® Shirt? A: Remove the ANASA® Reader. Place the ANASA® Shirt in the dedicated washing bag. Wash on a delicate cycle with liquid detergent only. Air-dry (no tumble dryer, ironing, or wringing). Q: Can I wash without the dedicated washing bag? A: No. It may damage the embedded inductive respiration sensors and void warranty coverage. Q: How should I clean the ANASA® Reader? A: Wipe gently with a soft, slightly damp cloth. Never submerge it in water or use solvents. Q: How do I store ANASA® System when not in use? A: Keep the ANASA® Shirt in its washing bag and the ANASA® Reader in its box at room temperature (10 °C to 30 °C), dry and away from sunlight or heat.

Data Access, Privacy and Security

Q: What data does ANASA® System record? A: Raw motion data, inductance signals from chest and abdomen, and optional short audio notes. Q: How do I retrieve and synchronize my data? A: We recommend using the ANASA® Fleet Manager for safe data transfer rather than removing the SD card manually. Connect the Reader via the provided USB cable and click the "Download data from all devices" button in the ANASA® Fleet Manager. This syncs files to a dedicated folder on your computer without overwriting. ⚠️ Important: Do not remove the SD card between data collection sessions (e.g., different data collection dates or participants). Use the software sync method to verify the previous session was captured. Q: How are data stored? A: The ANASA® Reader stores data locally on its internal microSD card (up to 64 GB) in .CSV format. Data can later be read by ATRIDE or an authorized research partner. Each file contains time-stamped sensor readings collected continuously during wear. Q: How are the data files named and organized? A: Each day that the ANASA® Smart Breathing Shirt is used, the ANASA® Reader automatically creates a new data file on the internal microSD card. The filename corresponds to the date and time when the first recording of that day begins (for example: 00121324.CSV, indicating the date in the format 00MMDDYY.CSV). If the ANASA® Smart Breathing Shirt is worn multiple times within the same day, all new recordings are appended to the same daily file, keeping all data from that day organized together. A new file is automatically generated on the next day the ANASA® System is used. Q: How are microphone recordings stored and named? A: When you use the built-in microphone, the ANASA® Reader saves each audio note as a .WAV file on the internal microSD card. Each recording can last up to one minute. The filename corresponds to the ANASA® Reader’s internal real-time clock (RTC) time at the moment the recording starts, stored in an encoded format. A decoding script is available to translate the filename back into the original timestamp if you choose to use the microphone feature. Q: Is my data anonymous? A: Yes. Data is stored anonymized and can only be accessed by ATRIDE or an authorized research partner. Q: Can I request my data to be deleted? A: Yes. You can request the deletion of your recorded data. Please contact ATRIDE (see Contact & Support section of this document) or, if you are participating in a study, inform the research team running the study. After receiving your request, your data will no longer be used and will be removed from active analysis where possible. Note that once data have been fully anonymised and detached from your identity, they may no longer be traceable back to you.

Charging & Battery

Troubleshooting

Q: The LED light on the side of the ANASA® Reader is not blinking red. Is data being recorded? A: No. If the Side LED is not blinking red, the device is not logging data. This is likely due to the device being in a "Hold" state. Cause 1 (Missing SD Card): If the SD card is removed or missing, the device stays on "hold" and will not record. Cause 2 (Low Battery): If the device was left uncharged (especially with BLE on) and the battery depleted, it may have written a final short file and shut down. Solution: Ensure the SD card is inserted, the device is charged, and perform a physical button reset until you confirm the blinking red light. Q: How do I troubleshoot signal loss or "4095/0" readings? A: If you observe "4095/0" data values while the Reader is connected to the shirt, this indicates a connection fault. Use a multimeter to check the continuity of the respiratory belts. If a band does not "beep" (no continuity), it is faulty and the shirt should be discarded or replaced immediately. Q: What happens if I swap SD cards? A: Data belongs to the specific SD card it was written to. If you observed a blinking red light during a session but cannot find the data, check if SD cards were mixed up between devices. The data exists on whichever card was inserted at the time of the blinking light.
