Pressure sensor

A method of determining a location of an applied force on a pressure sensor, comprising the steps of:

• providing a pressure sensor comprising:
• a substrate;
• a conductive layer disposed on said substrate, said conductive layer having a first thickness;
• a spacer layer having a second thickness which is larger than said first thickness;
• an elastic membrane connected to said spacer layer, said elastic membrane overlaying said conductive layer, said spacer layer providing a space between said elastic membrane and said conductive layer;
• and a sensing electrode layer arranged on a lower surface of said elastic membrane and spaced apart from said conductive layer;
• said sensing electrode layer forms at least two electrodes opposed and spaced apart from each other, said at least two electrodes comprising a first electrode and a second electrode;
• connecting said first electrode and said second electrode respectively to a first connector and a second connector;
• applying a pressure to said elastic membrane such that said first electrode and said second electrode contact said conductive layer to achieve an electrical connection;
• transmitting a first output signal of resistance data from said first electrode through said first connector to a processor;
• and
• transmitting a second output signal of resistance data from said second electrode through said second connector to said processor.
