  • Miniature camera device for stabilized video using shape memory alloy actuators
    Patent number: 11258951
    Abstract: An electronic device includes a gimbal driver and a digital camera. The digital camera includes suspension member(s) attached to a base. The digital camera includes a camera module supported by the suspension member(s). The camera module includes: (i) a lens that focuses an image; and (ii) a sensor attached to the lens and that detects the focused image. Shape memory alloy (SMA) actuator(s) are attached between the base and the camera module. The gimbal driver generates actuating signal(s) in response to movement of the base to stabilize the image. An electrical interconnect directs the actuating signal(s) from the gimbal driver to the SMA actuator(s) to rotate the camera module.
