Grand Challenges in Wearable Electronics

Abstract
Wearable technology has deep roots in history, with eyeglasses and wrist and pocket watches being two of the most prolific technologies still being in use today. These technologies developed and evolved over the centuries. For example, watches started as decorative pieces based on an oscillating wheel and gear mechanism, later acquiring a primitive form of energy harvesting (selfwinding), progressing to electromechanical and then to fully electronic devices Future watches may integrate sophisticated electronics, solar or thermal energy harvesting, carry a huge variety of functions beyond timekeeping and still be a decoration and a fashion statement. Eyeglasses is another vivid example, starting as assistive technology Eyeglasses are rapidly becoming a high-tech electronic device, with Google Glass, Alexa Frames, and the likes paving the way to everyday use of augmented reality. The long-term success of these two technologies is based on their utility, deep integration with daily activities, and social acceptance by the population These examples are very valuable when we consider the challenges facing wearable electronics today.
