We got the first prototype done, We interfaced the respiration sensing belt, Pulse Ox & Body temperature along with some early PWM controlled Textile Heating Pad.

An IRFZ44 N-mosfet was used to drive the Heating element using PWM control. We have a cheap USB boost regulator for giving a solid 7V supply for the Heating pad.

The respiration sensing belt is interfaced using detachable 10mm snaps. We have a 3-channel conductive ribbon cable soldered to an LM-35 temperature sensor too.

We soldered all of it into a half breadboard sized Adafruit Perma Proto board, We used one channel of power line for 7V supply and the other for 3.3V regulated supply from the Photon.
One glad coincidence with the permaproto is that the 55mm protoboard perfectly fit into one aluminium enclosure from Aliexpress I had lying around. Now a new problem arose as the enclosure would cover the chip antenna causing EMF sheilding. This was an easy fix thanks to the uFL antenna option given by the guys at Particle. I used a 2.4Ghz PCB antenna that was lying around.

As live baby trials were out of question for now, I had to test it on the brave Ser.Vignesh.
As you can see the belt is comfy to wear, The system is powered using a USB powerbank for now. Making a custom LiFePo4 battery pack is on my priority list.

This the back view of the system, We have a Fabric heating to warm my upper back with wires running to the MOSFET. Also you can see our custom 3d printed enclosure for PulseOx sensor, Will upload the STL files soon.
