  • Piezoelectric generator operated by fluid flow
    Patent number: 4005319
    Abstract: An electrical generator for projectiles and the like comprises a piezoelectric element housed in a cavity through which air is forced by missile movement. A reed-like tongue in the cavity has one end captive, its other end near a ram air inlet that terminates in a nozzle outlet which is aligned with the tongue and is so configured as to enable the ram air to impart vigorous vibration to the tongue. The piezoelectric element has a vibration transmitting connection with the tongue, near the captive end of the latter.
