1. A device, comprising:
- a component including an electroactive polymer (EAP) material configured to generate a voltage in response to movement of the component;
a voltage detector coupled to the component, the voltage detector configured to detect voltage generated by the component;
processing logic configured to perform a function based on the detected voltage;
a hinge coupling an upper portion of the device to a lower portion of the device, wherein at least a portion of the component is disposed in the hinge,wherein the component comprises a flexible strip that is configured to bend or un-bend when the device is opened, andwherein the processing logic is further configured to;
determine that the device is open based on the detected voltage.
