Thermal Energy Harvesting

In this paper, we describe a novel animal-tracking-system, solely powered by thermal energy harvesting. The tracker achieves an outstanding 100W of electrical power harvested over an area of only 2 times 20.5cm2, using the temperature difference between the animal’s fur and the environment, with a total weight of 286g. The steps to enhance the power income are presented and validated in a field-test, using a system that fulfills common tracking-tasks, including GPS with a fix every 1,1h–1,5h, activity and temperature measurements, all data wirelessly transmitted via (LoRaWAN) at a period of 14min. Furthermore, we describe our ultra low power design that achieves an overall sleep power consumption of only 8W and is able to work down to temperature differences of 0.9K applied to the TEG.

Thermal Energy Harvesting

Extracting an electrical energy from various environmental sources, called energy harvesting (or energyscavenging), has been an issue and attracting researchers attention in energy replenish networks.Thermal energy harvesting holds a promising future for generatinga small amount of electrical power to drive partial circuits in wirelessly communicatingelectronics devices. Reducing power consumption has also become a major challenge in wireless body area network (WBAN). The reliability ofthe WBAN is greatly dependent on the life span of theenergyaware routing in networks.In this paper presented a fuzzy controller for thermal energyaware routing in WBAN.The paper concludes with performance analysis of the thermal energy harvesting aware routing, comparison of fuzzy and other traditional energy management techniques,while also looking at open research areas of thermoelectric harvesting and management for wireless body area networks.

Thermal Energy Harvesting

A fully-integrated self-startup circuit with ultra-low voltage for thermal energy harvesting is presented in this paper. The converter is composed of an enhanced swing LC oscillator and a charge pump with decreased equivalent input capacitance. The LC oscillator has ultra-low input voltage and high output voltage swing, and the charge pump has a fast charging speed and small equivalent input capacitance. This circuit is designed with 0.18[Formula: see text][Formula: see text]m standard CMOS process. The simulation results show that the output voltage is in the range of 0.14[Formula: see text]V and 2.97[Formula: see text]V when the input voltage is changed from 50[Formula: see text]mV to 150[Formula: see text]mV. The output voltage could reach 2.87[Formula: see text]V at the input voltage of 150[Formula: see text]mV and the load of 1[Formula: see text]M[Formula: see text]. The maximum efficiency is in the range of 10.0% and 14.8% when the input voltage is changed from 0.2[Formula: see text]V to 0.4[Formula: see text]V. The circuit is suitable for thermoelectric energy harvesting to start with ultra-low input voltage.
