Development of haptic touch sensor that works by static
electricity

Super-micro, low-power sensors and devices that can
send and receive signals and information anytime, anywhere will
become an integral part of people’s lives in a hyper-connected
world driven by the Internet of Things (IoT). An important issue is
continually supplying electricity to the countless electronic
devices connected to the system. This is because it is difficult to
reduce the size and weight of the battery using the conventional
way of charging and changing it.
