Abstract
Systems and methods for detecting item placement on a surface are provided. The system includes a pressure-sensitive conductive sheet and a resistive grid connected to the pressure-sensitive conductive sheet. The resistive grid includes an electrically non-conductive polymer. The resistive grid includes one or more lines arranged in a pattern. The lines may include parallel lines, parallel and perpendicular lines, concentric circles, arcs of expanding radius, and/or any other suitable types of lines and/or any combination thereof. The resistive grid may include one or more distinct lines and/or shapes positioned at various points along the pressure-sensitive sheet layer.
