It is expected to be a great fit for a wide range of applications, including TWS (true wireless earphones), which are often used outdoors wearable devices like smart glasses and smart watches products used in the proximity of water, such as refrigerators, cooking appliances, washing machines, electric toothbrushes and bathroom remote controls and car dashboards.This article needs additional citations for verification. It can be mounted without cutting any holes in the enclosure, greatly improving the degree of freedom of design for products requiring small touch switches. PiezoTap also features an ultracompact and slim design, weighing only 0.046 grams and measuring 7 by 7 by 0.2 millimeters, and can be installed regardless of the enclosure’s material. By mounting PiezoTap inside the enclosure of a sealed device, applications where touch switches could not be installed in the past will become possible, greatly expanding the breadth of product design. It can be used even when gloves are worn or in wet environments, thanks to how it detects pressure utilizing the piezoelectric effect-converting the minute mechanical stress caused by the force from a touch into a voltage using a piezoelectric element. PiezoTap is an ultracompact, slim piezo switch built on the piezoelectric effect instead of the capacitance method. PiezoTap™, a compact, highly sensitive piezoelectric switch under development at TDK, solves the problems touch switches have had with gloves and wet conditions. Ultracompact, slim piezo switch solution built on the piezoelectric effect Since compact touch switches are expected to be utilized in wearable devices, outdoor products, and products used near water, there is a growing need to address issues surrounding these types of applications. Also, the presence of water or perspiration may cause erratic responses. With ordinary gloves, capacitance changes between the finger and the sensing area become difficult to detect, rendering the switch inoperable. Capacitive touch switches work by detecting the change in capacitance that occurs when a fingertip and a sensing area come into proximity.Ĭapacitive touch switches, however, bear a significant shortcoming: they are vulnerable to water and perspiration, and usage with gloves requires special conductive gloves. In particular, capacitive touch switches that respond to touches on screens have come into widespread use in smartphones and tablets in recent years. They are drawing substantial attention as they can replace mechanical buttons, improving product design and ease of use.īecause touch switches require no firm force to operate-all they need is gentle contact-they are commonly found in lights, automatic doors and elevators. Technical challenges facing the touch switch, a buttonless switchĪ touch switch (also known as a touch sensor) refers to a switch (sensor) that is activated when a person or object comes into contact with it.
