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.
