Piezoelectric actuators are widely used in industry, especially for their high-speed response and large force generation. In practice, a Piezoelectric Actuator Drive (PAD) is a crucial point to ensure the performance of the actuator. Our current applicatio ...
Soft pneumatic actuators (SPAs) are versatile robotic components enabling diverse and complex soft robot hardware design. However, due to inherent material characteristics exhibited by their primary constitutive material, silicone rubber, they often lack r ...
Underactuated systems offer compact design with easy actuation and control but at the cost of limited stable con- figurations and reduced dexterity compared to the directly driven and fully actuated systems. Here, we propose a compact origamibased design i ...

We present an electrically actuated tunable optical grating based on dielectric elastomer actuators. A simple fabrication protocol is presented, which integrates the grating with the actuating mechanism both made of soft elastomers, improving the tunabilit ...
Wearable technologies, interactive and safe robotic systems require an effective actuator control that highly depends on the accurate feedback from flexible and dense array of sensors. In this paper, we introduce a novel soft stretch sensor design that is ...

This work focuses on some promising applications of polyvinylidene fluoride (PVDF) based bimorph actuators in microengineering. The actuator of several centimeters in length and 100 mu m in thickness takes advantage of the structural and electromechanical ...
For more than a decade, Europe has been the wireless continent; today, wireless has almost completely shifted to the U.S. and Asia. This shift has had a profound impact on the electronic, semiconductor, and design ecosystem: long-time leaders have disappea ...
