INTRODUCTION

A small system on chip.

Serve as a Multi-purpose environmental monitor.

Implemented inside a body of human or animal.

To measures breathing, heart rate, temperature and PH levels.

ELECTRONIC MEDICAL PILL

WHY ELECTRONIC MEDICAL PILL ?

It monitors health parameters in real time environment.

Thus a human/animal can be diagnose in case of emergency.

POWER COMSUMPTION

Power Supply 1.8V to 3.6V

Total power and energy are defined as: Power =I x VEnergy=I x Time x V

CPU at active mode 230ϻA/MHz

Total watt power along the system is Twatt Twatt = A*V

= 230ϻA * 3.6V = 0.000828W

24

POWER COMSUMPTION

Selection of frequency at 433 MHz Twatt = 0.000828 * 433

= 0.3585 W

Total life cycle of the battery

Wh = Active power * total voltage along the system / 1000

For 120mAh

Wh = 120 * 3.6 / 1000 Wh = 0.432 hrs at 3.6 V

Total life cycle of 120mAh battery at 3.6V maximum is 1.205hrs
