Capacitive sensing technology

Cost-saving solution for replacing electromechanical components for switches, rotary and linear control touch switch / sensor solutions.

We can provide printed touch controls where the presence of a conductive object or finger creates a capacitance change which is converted into a switch activation in the customer application.
Piher, manufacturer of capacitive touch controls, can build this technology in several materials or substrates such as AG nanoparticle conductive inks, conductive polymer PEDOT, carbon and dielectric layers that allows flexibility, bendability  and other mechanical properties to be included in a wide range of flat or 3D surfaces.By using a translucent substrate, our films and touch sensors allow low cost, low power, low weight and low profile backlit designs. (i.e. led light goes through the substrate).

Benefits of Piher’s capacitive sensors:

− Low cost (reduction of component count, no whires, easier assembly).

− Energy-efficient (capacitive sensing wakes up the electronics and then it is ready for operation).

− Low weight (traditional PCB, buttons and wiring not needed anymore).

− Low power.

− Long life.

− Low profile.

− High sensitivity.

− Translucent ready for back-lit applications.

− Stable and robust (no moving parts to wear, circuitry can be escapsulated).

− Printing in FR4, CEM, CERAMIC and flexible substrates.

− Shape design freedom and curved surfaces sensors.

− High volume manufacturing capability and flexibility.
