Abstract: A sensing pad includes a first sensing layer, a second sensing layer and a spacer layer. The second sensing layer has at least one second sparse sensing zone and at least one second dense sensing zone. The spacer layer is disposed between the first sensing layer and second sensing layer, and includes at least one high pressure spacer zone and at least one low pressure spacer zone. The second sensing layer is pressed downwards upon receiving a load to compress the spacer layer and contact the first sensing layer to generate electric connection, thereby detecting the pressed location. Through the dense sensing zone and sparse sensing zone distributed on the second sensing layer whether a person is lay on a bed can be judged to reduce faulty judgments, and the posture of the person can be detected to better understand conditions of the person lay on the bed.

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.

Abstract: An induction pad includes a first induction layer, a second induction layer and a spacer layer. The second induction layer has at least one second sparse induction zone and at least one second dense induction zone.
