Abstract: The present disclosure provides a ubiquitous energy fusion and harvesting system, formed into a hexahedron by splicing light-heat-radio frequency (RF) fusion energy-harvesting devices, light-heat-kinetic-RF fusion energy-harvesting devices, and a heat-dissipating circuit board. The system can adapt to multi-directional and all-time solar energy harvesting, and multi-band and omnidirectional RF energy harvesting, avoiding insufficient output of electric energy in a harsh environment of single energy harvesting. In the present disclosure, a solar cell sheet serves to provide a heat source for a temperature difference power generation sheet, and a piezoelectric power generation array serves as a cooling fin to cool the temperature difference power generation sheet, realizing a multi-source ubiquitous energy composite harvesting and conversion with mechanism fusion and spatial mutual benefit.

The housing is configured to support and accommodate the photoelectric-thermoelectric energy harvesting apparatus, the piezoelectric energy harvesting apparatus, and a heat dissipation plate. The photoelectric-thermoelectric energy harvesting apparatus is respectively arranged on five surfaces of the housing to implement reciprocally coupled harvesting of solar energy and thermal energy in a working environment. The piezoelectric energy harvesting apparatus is arranged on a right side surface of an interior of the housing to implement reciprocally coupled harvesting of thermal energy and mechanical energy in the working environment.

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.
