The temperature dependence of the response of piezoelectric ‘‘bimorphs’’ ■ (■ Registered trademark of Vernitron Corp., Bedford, OH) has been studied. This response is markedly decreased as temperature is decreased. Since the bimorphs are voltage limited, the amount of motion available is thus reduced as the temperature is lowered. This effect is important in the design specifications for the use of bimorphs at low temperatures.
