Specifically, the gastrointestinal tract is of interest. This part of the body can be looked into with a swallowable wireless endoscopic pill. The pill contains different components such as different kinds of sensors, a microcontroller, a transmitter and the power supply. This thesis will discuss the power management of such a pill. The used parts are two CR1025 batteries at a voltage range of 4-6 V and capacity of 30 mAh, a TPS82150 switching converter at an efficiency of 85.8 % with an output voltage of 3.3 V, a TMP112B temperature sensor, a MS5534C pressure sensor and a CC2650 micro controller that consists of a main part (cpu), sensor controller part and a transmitter. The power used by the system was measured to be 2.74 mW per cycle. This resulted in a 57.69 hours runtime which leaves room for other sensors to be implemented and ensures a diagnosis of the whole gastrointestinal tract. All components have been put on a PCB and put into a 3D printed capsule of 123 mm in length and 33 mm in diameter.
