The input signal is buffered and enters the gain adjuster for gain setting. Meanwhile, the bias voltage generated by a temperature-compensated reference voltage generator can be set to an arbitrary value using a bias voltage adjuster and is added to the aforementioned signal before entering the output amplifier. The output amplification section receives the input signal through an operational amplifier, and to achieve high output, four MOS-type FETs are connected in parallel, further reducing impedance through a quasi-complementary circuit. Negative feedback is achieved by returning an inverted signal to the operational amplifier in the input section, and the output terminal is designed to cut off the output in case of overcurrent protection.

The pressure-driven piezoelectric actuator is a frame-integrated piezoelectric actuator that incorporates piezoelectric elements within a frame (pressure case). It is possible to create piezo actuators that meet your desired output force and displacement by combining the pressure case with piezoelectric elements of various standard sizes. Additionally, the pressure case complements the piezoelectric element's weakness to tension, making it a durable piezoelectric actuator.

1. High energy efficiency It is characterized by a very high efficiency of about 25% in converting electrical energy to mechanical energy. Additionally, to maintain a certain displacement state, it is sufficient to maintain a specified applied voltage, and the current when maintaining the voltage is effectively zero. 2. Capable of high-speed operation In general, it can operate at high speeds compared to actuators that utilize electromagnetic attraction. For the driving limit, which is the resonance frequency, please refer to the technical note "Operation under dynamic load." 3. Possible miniaturization and thinness Compared to actuators that utilize electromagnetic attraction to generate equivalent displacement and force, it is possible to achieve miniaturization, especially in terms of thickness. 4. Good controllability Since the relationship between voltage and displacement is almost proportional, it is possible to obtain a specified displacement through voltage control. However, due to the presence of hysteresis, the displacement generated at the same applied voltage will not be the same with changes in voltage (rise and fall), so a displacement sensor is necessary when precise displacement generation is required.
