A tactile sensor is a type of sensor made to recognize and quantify physical pressure or touch. Through physical contact, it is used to detect interactions between things and their surroundings. Numerous industries, including robotics, manufacturing, healthcare, consumer electronics, and more, use tactile sensors in a variety of applications.
The purpose of tactile sensors, regardless of their design or technology, is to transform mechanical force or pressure into electrical signals that can be detected and analyzed by electronic systems. A few examples of tactile sensors are as follows:
Tactile Resistive Sensors: These sensors are made up of two conducting layers that are spaced apart by a compressible substance. The distance between the conductive layers changes when pressure is applied, changing the resistance.
Sensors that detect touch or pressure by changing capacitance are known as capacitive tactile sensors. They are made up of a dielectric layer sandwiched between two conductive layers. The capacitance between the conductive layers is affected by pressure because it changes the spacing between the layers. The force applied is then calculated from this change in capacitance.
Piezoelectric Tactile Sensors: When put under pressure or under mechanical stress, piezoelectric materials produce an electrical charge. These sensors directly convert applied force into an electrical signal using piezoelectric materials.
The ability of devices and systems to detect and react to physical contact or pressure is made possible by tactile sensors, which improve their functioning and usability across a variety of applications.
The Global Tactile Sensor Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A 3D sensor powered by artificial intelligence (AI) that can give robots a feeling of touch has been released by GelSight. The sensor is robust enough to be used in robots and cobots, yet small enough to be comfortable in human hands. The sensor can deliver shareable data right out of the box in only five minutes.
The industry-first GelSight Mini tactile sensor is small, reasonably priced, and has a plug-and-play setup that allows customers to start using the tool in under five minutes after taking it out of the box.
For corporate research and development, academics, and hobbyists, GelSight Mini will lower the entry barrier into robotics and touch-based scanning while opening doors to new territories, like the Metaverse.
