Force sensing technology is being used more and more, Ultra-thin and soft,
The Force sensor (FSR sensor) is composed of polyester film with excellent
comprehensive mechanical properties, highly conductive materials,
and nano-level pressure-sensitive materials
The bottom layer is a flexible film and a conductive layer laminated thereon,
and the top layer is a flexible film and a pressure-sensitive material
laminated thereon. The two are bonded by double-sided tape, and the sensing
areas of the upper and lower layers are isolated.
pressure-sensitive nanomaterial
highly conductive material compounded on polyester film
double-sided adhesive paste and isolation
When the force sensing area is pressed, the disconnected lines at the bottom layer will be conducted through the pressure-sensitive layer on the top layer, and the resistance output value changes with the pressure
Ultra-thin
Thickness 0.2mm Various
sizes
