Abstract
A pressure sensing device utilizing force transducer ink comprises a resistive region deposited between a first and a second conducting region on a first insulating material, the resistive region electrically coupling the two conducting regions. On a second insulating material, a conducting region is deposited and a layer of force transducer ink is deposited over the conducting region. The two insulating materials are positioned in such a manner that the pressure transducer ink is in contact with the resistive region and separates the resistive and coupled conducting regions from the conducting region. A determination of the force applied to this configuration can be made by measuring the resistance between the first and second conducting regions. According to a second embodiment, a second resistive region and coupled conducting regions replace the conducting region on the second insulating material. By orienting the two resistive conducting element configuration, a position of a force applied to the pressure sensing device can be determined as well as the strength of the force.
