Pressure Sensitive Keys
First Claim
1. A pressure sensitive key comprising:
- a sensor substrate having one or more conductors; and
a flexible contact layer spaced apart from the sensor substrate and configured to flex in response to an application of pressure to contact the sensor substrate, the flexible contact layer having;
a first location that is configured to contact the sensor substrate using force sensitive ink; and
a second location that is configured to contact the sensor substrate using force sensitive ink such that the second location has increased conductivity than the first location.

Abstract
Pressure sensitive key techniques are described. In one or more implementations, a device includes at least one pressure sensitive key having a flexible contact layer spaced apart from a sensor substrate by a spacer layer, the flexible contact layer configured to flex responsive to pressure to contact the sensor substrate to initiate an input, for a computing device, associated with the pressure sensitive key. At least one of the flexible contact layer or the sensor substrate are configured to at least partially normalize an output resulting from pressure applied at a first location of the flexible contact layer with an output resulting from pressure applied at a second location of the flexible contact layer that has lesser flexibility than the first location.
