Features
Breathpal was developed to be for personal and professional usage, with following requirements as starting point:
- Low cost electronics and construction
- Suitable to wear daylong to gather breathing patterns while not paying attention to it
- Simple in use: no training required
This resulted in a device with the following features and properties:
- Easy attachment and operation by use of RIP strap poppers
- Instant working: No On/Off switch needed
- Small and light to allow invisible wearing: 6.2 x 3.0 x 1.2 cm, 20 grams, for the abdominal sensor, 3,9 x 3.0 x 1.2 cm, 13 grams, for thorax sensor. Straps 11 gram each
- Full day battery life and raw data storage. Recharging and bulk data retrieval over USB
- Accurate 2-ch RIP: resolution* up to 0.07 cm2 intersection surface change
- Low temperature drift and no mutual influencing between RIP bands
- Movement and orientation sensor: 3-D 12 bits accelerometer +/- 2G
- Temperature sensor: 1 0C resolution
- Tactile feedback by integrated vibration motor
- Sample speed 2.5 – 5 – 10 samples per second*
- Real Time Clock and Data stamps included.
- BLE 5.0 Wireless Communication for real time data communication using dedicated dongle
- Open and easy communication protocol; simple Windows presentation and storage tools
- Economical design, low cost at volume production
*: Resolution and sample speed can also be adapted on request
The sensor hardware is supported by Windows applications for data retrieval and sensor configuration, and firmware upgrade.
- Data retrieval and storing to .csv text
- Live graph of both channels and accelerometer, live writing to file
- Fully disclosed communication protocols
