Of course there’s also pneumography via radar that could be rolled into this sensor suite. And speaking of electrodes, we’re intrigued by the ADS1292 chip uses, which not only senses the heart’s electrical signals but also detects respirations by the change in impedance as the chest wall expands and contracts.
It’s not entirely wireless – the fingertip pulse oximetry dongle and chest electrodes still need to be wired back to the central unit – but the sensors all talk to a Teensy 3.2 which then communicates to an Android app over Bluetooth, so there’s no need to be tethered to the display. Pulse, ECG, respiration rate, galvanic skin response, and body temperature are all measured from one compact, wrist-wearable device. Starting with an automatic blood pressure cuff that had previously reversed engineered, he started adding sensors. And from the look of it, ’s system might even monitor a few more parameters than ’ bleeping bed from the original series. Is it ’s long-awaited sickbay biobed, with wireless sensing and display of vital signs? Not quite, but this wearable patient monitor comes pretty close.
