Drive method for bending flat elastic plates - attaching polarised crystal plates to flexible plate and applying voltage to cause expansion by reverse piezo-effect |
摘要 |
A drive method for producing curving motion to bend flexible plastic plates involves joining one or more polarised crystal plates (2) to the flexible plate (1). When a voltage is applied to the crystal plates, they expand according to the reverse piezo effect, thus bending the flexible plate. Two crystal plates can be joined together so that, when a voltage is applied to one and a voltage is removed from the other, they undergo a common bending. USE/ADVANTAGE - For bending predominantly flat plates. The method is simply implemented without the need for heating.
