Abstract
Touch sensors have a wide range of applications in smart homes, enabling the control of lighting, air conditioning, curtains, and other equipment. This paper summarizes the principles, applications, and future developments of touch sensors, including capacitive, resistive, and piezoelectric sensors. The capacitive touch sensor operates based on the capacitance formula, the resistive sensor on the resistivity formula, and the piezoelectric sensor on the piezoelectric effect. Capacitive touch sensors can detect the movement and position of objects and respond quickly, but they require power. Resistive sensors have a fast response time, long durability, low cost, and high sensitivity, but they also require power. Piezoelectric sensors do not require power, can detect dynamic physical quantities, but are unable to detect static ones. Both capacitive and piezoelectric sensors are used in smart mobile devices, while resistive sensors are used in all-in-one machines. Given their principles and current applications, touch sensors are expected to be utilized in the touch screens of operation interfaces in more machines and the bionic skin of androids.
