Energy harvesting, from a diverse set of modes such as light, temperature or motion, has been viewed as the key to developing battery-less sensing devices. We have recently demonstrated the capability to harvest RF energy from WiFi transmissions, applying it to power a prototype wearable device that captures and transmits accelerometer sensor data. Our solution, WiWear, has two key innovations: 1) beamforming WiFi transmissions to significantly boost the energy that a receiver can harvest ∼3-4 m...

Many battery storage systems are located in unattended or remote sites. Thus, unexpected premature battery failure cannot be discovered easily and accurately without on-site visual inspection regularly. To ensure serviceability, those batteries are typically replaced after a few years of service, depending on the site condition and the maintenance practice and experience of the operators. The proposed diagnostic technology can conduct real-time estimation of the state-of-charge (SOC) and state...
