Trillions of sensors are envisioned to achieve the potential benefits of the internet of things. Realizing this potential requires wireless sensors with low power requirements such that there might never be a need to replace a sensor’s power supply (e.g. battery) over the lifetime of that device. The battery lifetime of wireless communications devices is often governed by power consumption used for transmitting, and therefore transmit power amplifiers used in these devises are important to their commercial success. The efficiencies of these power amplifiers are set by the capabilities of the semiconductor transistor devices that drive them. To achieve improved efficiencies, researchers at UC Berkeley have developed a novel method and structure for realizing a zero-quiescent power trigger sensor and transceiver based on a micromechanical resonant switch. This sensor/transceiver is unique in its use of a resonant switch (“resoswitch”) to receive an input, amplify it, and finally deliver power to a load. This novel technology also greatly improves short-range communication applications, like Bluetooth. For example, with this technology, interference between Bluetooth devices would be eliminated. Also, Miracast would work, despite the presence of interfering Bluetooth signals.
