Energy consumption optimization for thermal energy harvester applications

Abstract

This paper demonstrates the concept of node consumption reduction for IoT applications. The main emphasis is placed on the autonomy of the whole device, which must be independent of external power supply. That is why energy harvesting based on temperature principle is used for power supply. One of the parameters monitored is the service uptime. The concept of intelligent control of the individual parts of the equipment leads to significant energy savings. This control requires the use of low power components, but only their appropriate connection and mutual monitoring of their operating modes leads to the desired savings. This algorithm can be adapted to the needs of IoT nodes focused on real-time performance applications or the process tracking slow low power applications. This concept will ultimately be adapted to a wireless node for monitoring position and temperature for use in medical applications to monitor the patient's position on the bed or position while moving.
