Abstract
A pressure measurement member includes an insulation bottom layer, a flexible insulation top layer and at least one spacer. The insulation bottom layer has a bottom conductive element on the surface thereof. The flexible insulation top layer has a top conductive element on the surface thereof adjacent to the insulation bottom layer and opposite to the bottom conductive element. The spacer is located between the insulation bottom layer and flexible insulation top layer to separate the insulation bottom layer and flexible insulation top layer. As different pressures could result in different impedance variations on the contact area between the top conductive element and bottom conductive element, the pressure being applied can be derived from the impedance variation. The invention can measure pressure without using piezoresistive material to reduce cost.
