1. A liquid lens apparatus, comprising:
a first substrate comprising:
a central portion, and
a peripheral portion outside of the central portion; and
a lithographically formed sensor on the peripheral portion of the first substrate such that the lithographically formed sensor is on an exterior surface of the liquid lens apparatus,
wherein when the lithographically formed sensor is on the exterior surface of the liquid lens apparatus, the lithographically formed sensor detects a temperature of the liquid lens apparatus, enabling the liquid lens apparatus to compensate for thermal expansion or contraction of the liquid lens apparatus resulting from changes in the detected temperature of the liquid lens apparatus.
