The Potential of an Ultracompact Piezo Touch Switch Usable with Wet Hands

Touch switches are found in smartphones and a variety of other devices. They are conducive to aesthetic design, convenient to use, and are growing rapidly in popularity. However, they are vulnerable to water and perspiration and largely unusable when gloves are worn. PiezoTap™, currently under development at TDK, is a piezo switch based on piezoelectric technology that is expected to expand the potential of touch switches.
