Abstract :
Integration of betavolatics with radioisotope-powered piezoelectric micropower generators (RPG) operating in new resonant modes, attains nuclear-electrical conversion efficiencies of up to 30%, generating 1 to 10muW peak power with 1 to 10 milliCurie of Nickel-63. A 20mV-voltage-drop ac-to-dc rectifier employing radioactively biased MOSFETs is developed for efficient conversion of RPG-generated low-amplitude power signals
