Concept of Low-Power Sensor Network Module for Diagnostic of Stomach Diseases in Cows

This paper presents the stages of developing a power supply system for a probe placed in the stomach of a cow. The power supply system is based on Triboelectric affect. To evaluate the operation, a triboelectric nano generator was built. The triboelectric nano generator has been tested in three different ways. Work at low frequency, work at high frequency and work at high frequency with a connected energy storage. At the next stage, it was necessary to conduct motion tests to obtain information about the mechanical energy produced by a cow or other individual. To do this, a measuring device was built and tested, tests included measuring the duration of work in a wide temperature range and under strong mechanical stresses, were carried out for six weeks. To obtain vibration data, the device was mounted on the human body. Data was taken during the day. The measured data were used for the average energy produced by a person's movement during the day. As a result, it was stated that in order to obtain the necessary power for supplying the probe, it is necessary to produce a triboelectric nano generator with a total surface area of 2.5 [sq. m.]. Which is realistic using nanostructures.
