Printed capacitive pressure sensors on plastic film
An intelligent plastic film used as a large area sensor for weight and position detection.
The weight is measured by the mechanical action released by placing an object on the pressure sensor film. The placing pressure produces an electrical signal and the weight of the object can be measured. After removing the object from the pressure sensor film, it goes back to the original state. This process can be repeated arbitrarily and immediately following the previous measurement. The position is detected by the allocation of marked electrodes on the predefined, matrix arranged raster.
Objects can be identified, exactly located and its shape can be defined. This information can be accessed in real time.
The plastic electronic pressure sensor film is a particular flexible, bendable, lightweight, customisable and cost efficient solution; which offers many advantages for several of business branches. The robust surface and the possibility to produce a large area sensor in mass production distinguish the plastic electronic pressure sensor film from competitive products.
