Electricity yourself? Batteryless microchip

As 5G begins to be commercialized, the IoT market, which connects things to the Internet, is also drawing attention. However, IoT devices are also pointed out as one of the factors that reduce the possibility of IoT because they cannot be placed only in places that require power supply and can secure power. However, through Energy Harvesting, a microchip that operates without the need for a battery comes out and draws attention.

ONiO.zero is a battery-free microchip developed by ONiO. Since it is low-power and can produce power directly, it has the necessary characteristics of a battery such as a coin battery and a lithium-ion battery. Devices using batteries require maintenance such as battery replacement, but ONIOZERO can supply power to sensors and devices for several years without worrying about such maintenance. In addition, it can be said that small electronic devices do not require batteries, which occupy most of the space, so they are highly compatible with clothes, watches, and medical devices.

The architecture adopted by this product is RISC-V, and the clock frequency depends on the available input voltage. 1.8V is 24MHz, 1.0V is 6MHz, and 0.8V is 1MHz. Bluetooth LE is adopted as the wireless communication standard, and industry standard communication standards such as 12C, SPI and UART can be used for communication with peripheral devices.

An important energy source is a high-frequency rectifier inside the chip, and the frequencies correspond to the 800, 900, 1800, 1900 and 2400MHz bands. Related information can be found here .
