Monolithically Integrated Sensing, Communication, and Energy Harvester

Abstract

Both energy and information are different manifestations of light. Using light to offer the coexistence of sensing, communication, and energy harvesting functionalities, monolithically integrated III‐nitride diode system toward the Internet of Things is dealt with. The III‐nitride receiver is capable to convert optical signals into electronic ones and forward them to the transmitter. The energy harvester generates electricity from light to turn on the transmitter, which, in turn, can transmit information optically to other proximally located devices for analysis or relay the data over longer distances. This monolithic III‐nitride optoelectronic system can simultaneously achieve wireless energy harvesting and communication through light. The truly self‐powered, integrated III‐nitride system is a paradigm change where the previously competing sensing, communication, and energy harvesting operations can be jointly implemented on a single chip.
