1. A sensor comprising:

  • a sensor layer patterned with conductive elements spread across the sensor layer, wherein the conductive elements are electrically isolated from one another and wherein the sensor layer is configured for capacitive based sensing; and

    a resilient layer formed with spacer dots coated with a hard coat film and positioned proximate to the sensor layer, the sensor layer configured to detect local changes in capacitance based on pressure applied to the resilient layer,wherein the spacer dots are formed from a material having a hardness of between 20-40 durometers.
