“…1c , each harvesting unit interconnects with the LED via metal wires. To achieve high open-circuit voltage ( V oc ) and consequently power the micro-LED 39 , the two 1 × 2 mm 2 QWDs connected in a series have merged to form an energy harvester, which will convert coded light into electrical energy and signals through the photovoltaic effect. Figure 1d illustrates a cross-sectional scanning electron microscope image of a 2.28 μm-thick SiO 2 /TiO 2 DBR that is deposited on the device surface by using optical thin film coater.…”

Wireless technologies can be used to track and observe freely moving animals. InGaN/GaN light-emitting diodes (LEDs) allow for underwater optical wireless communication due to the small water attenuation in the blue-green spectrum region. GaN-based quantum well diodes can also harvest and detect light. Here, we report a monolithic GaN optoelectronic system (MGOS) that integrates an energy harvester, LED and SiO2/TiO2 distributed Bragg reflector (DBR) into a single chip. The DBR serves as waterproof layer as well as optical filter. The waterproof MGOS can operate in boiling water and ice without external interconnect circuits. The units transform coded information from an external light source into electrical energy and directly activate the LEDs for illumination and relaying light information. We demonstrate that our MGOS chips, when attached to Carassius auratus fish freely swimming in a water tank, simultaneously conduct wireless energy harvesting and light communication. Our devices could be useful for tracking, observation and interacting with aquatic animals.

“…The "Internet of Things" (IoT) can connect many devices at the edge of the net that gather, analyze, and transmit data. [1][2][3][4] Providing operational power to these devices deployed in remote or inaccessible areas is critical to the practical implementation of the IoT. [5][6][7][8] In particular, monolithically integrated systems that incorporate sensing and communication functionalities and energy harvesting infrastructure are highly required.…”

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.
