Abstract
Embodiments are generally directed to methods and apparatuses having electronic device cover glass that includes embedded sensors. In particular, one embodiment may take the form of a device having a device housing and a cover glass coupled to the device housing. The device includes a plurality of sensors coupled to the cover glass and configured to acquire data related to stress and strain experienced by the cover glass. The plurality of sensors is embedded within the cover glass.
Claims12
A portable electronic device comprising:
- a portable electronic device housing;
- a cover glass coupled to the portable electronic device housing;
- and
- a plurality of sensors coupled to the cover glass and configured to acquire data related to stress and strain experienced by the cover glass, wherein the plurality of sensors are embedded within the cover glass and coplanar with an external surface of the cover glass.
An instrumented cover glass for a portable electronic device comprising:
- a cover glass layer;
- a plurality of sensors embedded in an internal surface of the cover glass and coplanar with said surface;
- and
- a backing layer in contact with said internal surface, wherein the backing layer sandwiches the sensors with the cover glass, the cover glass and the backing layer forming a unitary structure.
A method of operating an instrumented cover glass in a portable electronic device comprising:
- operating a plurality of sensors embedded in, and coplanar with, a surface of the instrumented cover glass;
- sensing an impulse event with the embedded sensors;
- logging the sensor data into a memory;
- extracting the sensor data from the memory;
- and
- processing the sensor data to determine areas of stress on the cover glass.
