Nikola Labs Technology

Nikola Labs’ wireless power technology is based on a novel RF energy harvesting circuit invented by CTO Dr. Chi-Chih Chen, while he was a research professor at OSU’s world-renown Electroscience Laboratory. The technology, known as radio frequency to direct current (RF to DC), works by sending a RF signal from an existing or dedicated transmitter to a receiving device that interprets radio waves into realizable power. The interpretation is done by first capturing the RF energy on an antenna, rectifying the wave, boosting voltage and managing the DC power to charge a storage element of directly operate a device.

INDRA

The heart of Nikola Labs’ solutions is the tiny INDRA chip, which measures only 5.6mm x 3mm x 0.8mm. Developed with Texas Instruments and Skyworks Solutions, INDRA is a miniaturized version of Nikola Labs’ efficient RF-to-DC circuitry. INDRA was specifically designed to power Internet of things (IoT) devices, such as industrial sensors, which with the addition of wireless power can provide uninterrupted data without the need to ever change batteries.

Features of INDRA include:

    State-of-the-art RF-to-DC rectifier using Skyworks Solutions diodes

    • Low forward voltage suitable for harvesting low-power RF signals

    Power management optimized for ultra-low power applications

    • Efficient as low as 15 uW
    • 330mV cold-start

    50% Maximum Power Point Tracking (MPPT)

    • Regulated 3.3 V DC output

    External antenna and impedance matching

    • Maximum application flexibility
    • Works over a wide range of frequencies – 300 MHz to 6 GHz
