Abstract
A deflectable substrate such as a phenolic resin has a conductive ink deposited thereon in a pattern preferably with a segmented conductor positioned on top to form a flexible potentiometer in which the resistance consistently and predictably changes upon deflection or the bending of the substrate.
Claims19
A flexible potentiometer, comprising:
- a flexible insulating plastic substrate;
- and
- a conductive material applied to the substrate, the conductive material having a resistance which consistently and predictably varies as the substrate and conductive material are bent.
A flexible potentiometer, comprising:
- a flexible substrate;
- and
- a flexible conductive material applied adjacent to the substrate, the conductive material having a resistance which varies as the conductive material is bent.
A flexible potentiometer system, comprising:
- a flexible insulating substrate which is bendable between a first and a second position;
- a conductive material adhered adjacent to the substrate, the conductive material having a resistance which consistently and predictably varies as the conductive material is bent between the first to the second position;
- and
- an electrical measuring circuit connected to the conductive material that provides a value to a parameter that is indicative of the mount of bending.
