Abstract
A membrane switch in which a first conductive part is formed on a first substrate, a second conductive part is formed on a second substrate, and the substrates are layered via a spacer such that the conductive parts face each other with a space therebetween, and an organic material showing piezoelectricity is filled, or disposed in the space such that an air gap is present, are useful for obtaining an output signal corresponding to an applied pressure.
Claims30
A membrane switch, comprising a first conductive part formed on a first substrate and a second conductive part formed on a second substrate, wherein the first substrate and the second substrate are layered via a spacer such that said first and second conductive parts face each other with a space therebetween,
- wherein
- an organic material showing piezoelectricity is filled in said space, or
- an organic material showing piezoelectricity is disposed in said space such that an air gap is present between said organic material and one of said first and second conductive parts.
