Tactile sensor overview
What are tactile sensors?
Tactile sensors, also known as tactile force sensors, are digital devices for measuring pressure. Aspects of performance such as definition vary between tactile sensors, and the correct type must be selected for each application.
Visualizing the extent and distribution of pressure has applications in research and development, analysis and quality improvement across a range of fields. It is widely used in industries relating to automotives, electronics, paper manufacturing, packaging for food and pharmaceutical products, and ergonomics.

Working of tactile Sensor
Most pressure tactile sensors work based on one of two main principles, piezoresistance and capacitance. Converting pressure into electrical signals using these methods enables pressure mapping to be performed on a computer or similar device.
Types of tactile sensor
Tactile sensors come in a variety of shapes and sizes depending on the application, and the correct type must be selected in advance. The configuration required to achieve the right specifications also varies depending on the situation.
For example, when measuring the grip force and shape of the digits when an object is held in the hand, a suitable dedicated sensor must be found and its use must be mastered. Biometric tactile sensors are a particular type of tactile sensor that convey tactile feedback from robots with human-like hands. In the field of robotics, special sensors are often used by placing them in an array on the part to be measured.
Application Examples for tactile sensors
Tactile sensors are suitable for measuring pressure dynamically. This includes uses relating to ergonomics, such as golf equipment, bicycle saddles, mattresses and physical examinations (measuring pressure on the soles of the feet, etc.) They are also used for more specialized applications in areas such as nursing care.
Pressure measurement tool "Prescale"
What is Prescale?
Prescale is a type of pressure mapping film, another tool for pressure mapping.
It is an analog tool that enables pressure mapping using the density of the red patches that appear on the thin film when pressure is applied.

It can be used proficiently in a short time, enabling any user to perform measurements with ease.
Freely customizable shape
As Prescale has no wiring, it can be cut to any size and shape as required.
It is even capable of measuring parts with irregular shapes or holes.

Freedom to measure in a range of locations
Measurement is simple, only the film is required.
Enables measurements in:
- Confined spaces
- Areas without power supply or internet access
- Locations that cannot be accessed with a computer
Prescale use cases
Prescale is widely used at R&D and production sites in the automotive industry, the food and pharmaceutical product packaging industry, and industries involved in the manufacture of electronic components such as substrates, lithium ion batteries and semiconductors. In addition to checking contact between parts, it is used to check nip pressure, winding pressure, compression pressure, and tightening pressure.
