Sensebridge Meeting Notes about Pulse Choker
Research Links
12 lead ECG fabric electrode belt system patent
Wearable ECG Monitoring System Using Conductive Fabrics and Active Electrodes
Preliminary study of dry knitted fabric electrodes for physiological monitoring
FDA clearance on Textronic fabric ECG electrodes
Eric has filled out the "purchase" form on Textronics fabric electrode kit, and will follow up with them in order to get the kit. Rachel, Chung-Hay and Eric will split the cost.
Optical Pulse Circuit Experimentation
We soldered leads unto the emitter/transmitter device, and held it against various body parts:
- Neck: no flashing, despite many attempts on both of us
- Wrist: Eric got it to work once on his wrist, but generally this fails
- earlobe: Eric got it to work a few times, this was actually the most promising area after thumb
- Thumb/finger: the original, still very flaky, works maybe 25% of the time
Prototype Armature/Display
We prototyped a choker today. We cut a "T" circuit silk screen mask out of a cool piece of flexible plastic, and then painted the silver conductive paint unto the mesh fabric. Then we soldered multi-color cycling LEDs unto the traces, and wires unto the dongle end, and stuck them into an arduino.
Code:
int LeftNeckLED = 6; int RightNeckLED = 8; void setup() { pinMode(LeftNeckLED, OUTPUT); pinMode(RightNeckLED, OUTPUT); digitalWrite(LeftNeckLED, 1); digitalWrite(RightNeckLED, 1); } void loop() { digitalWrite(LeftNeckLED, 1); digitalWrite(RightNeckLED, 1); delay(500); digitalWrite(LeftNeckLED, 0); delay(6000); digitalWrite(RightNeckLED, 0); delay(30000); }
