Touch Sensor
It is also known as tactile sensor. It enables the device to respond to the physical touch when applied by the user. It is commonly used in smartphones. It works on the principle of the pressure. There are variety of touch sensors. Some of them are listed below:
- Capacitive Touch Sensors: It works when capacitance changes. The capacitance change due to inductive object like our fingers touch the screen of the phone.
- Resistive Touch Sensors: It is made of two flexible layers. There is a space between the two flexible layers. When pressure is applied, the top layer comes into contact with the bottom layer which causes change in the performance.
Sensors in Electrical Engineering
Sensors are the detection devices of the digital world. It senses the physical change in the environment and converts the sensed data into machine-readable or understandable language. The sensors are of two types i.e., analog and digital sensors. As the name suggests, an analog sensor provides analog values which is a set of infinite values. On the other hand digital sensor converts the data into digital signals which is a set of finite values. There are various types of sensors that are being used in various fields like the automation industry, healthcare sector, and many more.
In this article, we will study sensors, types, and practical applications.
