Wireless power transfer has been around for a long time. The “crystal set” or “crystal radio” over 100 years ago used the power carried in the radio signal to produce sound without any amplification or receiving circuit power source. Early spark gap transmitters also used tuned wireless power transmission. Now the circuitry is more sophisticated […]

Augmenting touchless gesture recognition with haptic feedback
By Vicky Messer Ever since the development of the trackball in the 1940s and the consumer release of the computer mouse in the 1980s, engineers have sought to push the limitations of computer-human interaction in an attempt to achieve a more intuitive and natural user experience. An obvious avenue to explore has been the gestures […]
