“Technology News: Researchers have successfully proposed a bidirectional piezoelectric linear actuator that uses the principle of bidirectional spiral clamping to achieve bidirectional high thrust actuation. Through careful design, the actuator performs excellently under tensile and compressive loads, with a maximum output force of 190 N, a maximum speed of 2.58 mm/s, and a stroke of 60 mm. This achievement provides strong support for the research and application of piezoelectric linear actuators, and is expected to promote rapid development in related fields.”
