Systems and methods for dynamically managing power consumption in an ultrasound device are provided herein. A transducer in an ultrasound device may have transmit and receive elements for respectively transmitting and receiving ultrasound signals. In at least one embodiment, the method includes sensing a motion of the transducer by a motion sensor that is coupled to the transducer. An amount of power consumed by the ultrasound device is then reduced, based on the sensed motion of the transducer. Reducing an amount of power consumption may include adjusting one or more operational parameters of the ultrasound device, such as but not limited to reducing the display frame rate, the receive aperture, or the transmit amplitude, or by decoupling power to one or more components of the ultrasound device. Alternatively or in addition, power consumption may be reduced based on signals received from a capacitive sensor and/or a patient contact sensor.
