1. A medical device for delivering fluid to a body or sensing body analyte, the medical device comprising:
- a pumping mechanism;
a driving mechanism for activating said pumping mechanism to dispense fluid; and
a power source housed in the medical device and electrically coupled to said driving mechanism and having an energy storage device for providing a pulsed power to activate said driving mechanism, wherein the pulsed power operates periodically between an accumulation mode in which the power source charges the energy storage device and a release mode in which the energy storage device delivers the pulsed power; and
a DC-DC converter to increase voltage of the pulsed power delivered in the release mode to the driving mechanism by the energy storage device.

Abstract
Devices and methods for powering a medical device for sustained delivery of fluids or continuous monitoring of body analyte are disclosed. The devices may comprise a pumping mechanism, a driving mechanism for activating the pumping mechanism to dispense fluid, and a power source coupled to the driving mechanism and having an energy storage cell for providing a pulsed power to the driving mechanism. The methods may be implemented by activating the driving mechanism using pulsed energy in the form of at least one pulse train pattern accumulated in and discharged from an energy storage component.
