  • Liquid lens design variant with temperature sensor on the outside
    Patent number: 11815732
    Abstract: A liquid lens apparatus includes a first substrate and a sensor. The first substrate has first and second opposing surfaces, a central portion, and a peripheral portion outside of the central portion. The sensor is formed lithographically on either the first or second surfaces of the peripheral portion of the first substrate such that the sensor is on an exterior surface of the liquid lens apparatus. The sensor is configured to detect a temperature of the liquid lens apparatus to enable compensation for thermal expansion or contraction of the liquid lens apparatus resulting from changes in temperature of the liquid lens apparatus.
