Abstract
A portable electronic device may include an electrical resistance sensor and a battery assembly being adjacent to the electrical resistance sensor. The electrical resistance sensor is positioned to be compressed when the battery assembly swells, and the electrical resistance sensor further includes a pressure sensitive material that exhibits a characteristic of changing an electrical conductance when compressed.

A portable electronic device, comprising:
- an electrical resistance sensor;
- and
- a battery assembly being adjacent to the electrical resistance sensor;
- wherein the electrical resistance sensor is positioned to be compressed when the battery assembly swells;
- wherein the electrical resistance sensor further includes a pressure sensitive material that exhibits a characteristic of changing an electrical conductance when compressed.
A method of detecting an increased size of a battery, comprising:
- determining a battery has an increased sized based, at least in part, on a signal exhibiting a changed electrical conductance where the signal is from an electrical resistance sensor that includes a pressure sensitive material that exhibits a characteristic of changing electrical conductance when the pressure sensitive material is compressed.
A computer-program product for use in a portable electronic device, the computer-program product comprising a non-transitory computer-readable medium storing instructions executable by a processor to:
- detect swelling of a battery assembly incorporated into the portable electronic device when an electrical resistance sensor is compressed and the electrical resistance sensor is incorporated into the portable electronic device where the electrical resistance sensor includes a pressure sensitive material that exhibits a change in electrical conductance when compressed.
