Abstract
AbstractThermoelectric‐photoelectric integrated power generator and a power management circuit are designed in this letter for the inefficiency of power amplifier and the generation of massive heat of transceiver. Thermoelectric‐photoelectric integrated power generator is composed of thermoelectric power generator at surface layer and photoelectric power generator at bottom layer, absorbing both heat and light energy at the same time. The outputs of thermoelectric and photoelectric power generator are connected with power management circuit after parallel connection. Power management circuit is an interface circuit which is able to boost the small output voltage of integrated power generator from 300 mV to 3.1 V with no external power supply. The innovation is not only structure integration, but also output integration of two power generators. In addition, 3.1 V voltage from power management circuit is compatible with most interfaces in transceiver system. The integrated power generator and power management circuit form a complete power supply module for transceiver and wireless sensor node.
