Abstract: A hybrid energy harvesting apparatus for harvesting omnidirectional multi-band radio frequency (RF) energy and thermoelectric energy includes a housing, an RF harvesting apparatus, a thermoelectric harvesting apparatus, and an energy storage apparatus. The housing is a hollow polyhedron. The thermoelectric harvesting apparatus includes a thermoelectric sheet applied to an outer side surface of the housing and a thermoelectric conditioning circuit mounted in the housing. The thermoelectric sheet is configured to harvest thermal energy and convert the thermal energy to electrical energy. The RF harvesting apparatus includes a multi-band two-dimensional antenna array tightly attached to the thermoelectric sheet and an RF-DC conditioning circuit mounted in the housing. A multi-band two-dimensional antenna in the multi-band two-dimensional antenna array is configured to harvest RF energy and convert the RF energy to electrical energy and dissipate heat from the thermoelectric sheet. The RF-DC conditioning circuit is connected to the multi-band two-dimensional antenna.
