Claims20
A system for detecting item placement on a surface, comprising:
- a pressure-sensitive conductive sheet that includes a resistive grid that is formed of an electrically non-conductive polymer.
A method for detecting item placement on a surface, comprising:
- placing an object onto a pressure-sensitive conductive sheet,
- wherein the pressure-sensitive conductive sheet includes:
- a top conductive layer;
- a bottom conductive layer;
- and
- an electrically conductive pressure-sensitive sheet layer interposed between the top conductive layer and the bottom conductive layer,
- wherein the pressure-sensitive sheet layer an electrically non-conductive polymer forming a resistive grid, and
- wherein placing the object onto the pressure-sensitive conductive sheet applies pressure against the pressure-sensitive conductive sheet;
- measuring, using a sensor, a change in resistance of the pressure-sensitive conductive sheet;
- and
- based on the change in resistance, determining that an object has been placed onto the pressure-sensitive conductive sheet.
