mm-Wave Ultra-Low-Power Wireless Sensing
Sensor nodes autonomous from power-supply
Millimeter-Wave (mm-wave) wireless communication provides several GHz ISM bandwidth using high data rate communication in short bursts with high duty-cycle for lowest power systems. Combined with an on-chip wireless power receiving technique, an on-chip antenna, a fully integrated monolithic passive mm-wave sensor node for internet of things (IoT) can be realized. Such a sensor node is autonomous from an external power-supply, as well it can sense the environment, receive commands and transfer the sensing information.
How to overcome the bottleneck of power consumption for mm-wave circuits
In order to overcome the challenge of the power consumption of mm-wave circuits for achieving monolithic passive sensor nodes, Hao Gao focuses on transceiver architectures and RF circuit techniques. He especially pointed out the demand of smart circuit solutions to enable power-autonomous wireless systems for IoT applications focusing on the harvester circuits and receiver architectures and implementations employing integrated antennas for 60GHz wireless operation for smallest possible sensor nodes.
