Basically multi-channel sensor used for biomedical
* When swallowed it travel the GI tract, detect
abnormalities and transmit data.
* Used for real time measurement of parameters
like temperature, pH, conductivity and dissolved
oxygen
* The sensors are fabricated using electron beam
and photolithographic pattern integration
CAPSULE
* Outer casing is made with chemically resistant polyether-terketone
* PCB chip carrier act as a common platform and is made from fiber
* Sensors are attached to the chip carrier using 10 pin polyamide ribbon connector and flat cable plug
* Sensor chips are connected to the both sides of the PCB
* The unit is powered by two STD, 1.55V Silver Oxide cells with a capacity of 175mAh
* The capsule is machined as two separate screw fitting compartment
* The sensor chips are exposed to the ambient environment through access ports and are sealed by 2 stainless steel clamps
* The complete prototype is 16 * 55 mm and weighs 13.5g including batteries
