Force concentrator techniques are described. In one or more implementations, a pressure sensitive key includes a sensor substrate having a plurality of conductors, a flexible contact layer spaced apart from the sensor substrate and configured to flex to contact the sensor substrate to initiate an input; and a force concentrator layer disposed proximal to the flexible contact layer on a side opposite the sensor substrate. The force concentrator layer has a pad disposed thereon that is configured to cause pressure applied to the force concentrator layer to be channeled through the pad to cause the flexible contact layer to contact the sensor substrate to initiate the input.
