On-Chip Micro Mixer Driven by Elastic Wall with Virtual Actuator
Micromachines, 2021 In this paper, we propose an on-chip micromixer driven by an elastic wall with a virtual actuator. The on-chip micro mixer is composed of a circular chamber surrounded by a ring-shaped channel under isolation with an elastic wall.

Continuously-variable series-elastic actuator [PDF]
2013 IEEE 13th International Conference on Rehabilitation Robotics (ICORR), 2013 Actuator efficiency is an important factor in the design of powered leg prostheses, orthoses, exoskeletons, and legged robots. A continuously-variable series-elastic actuator (CV-SEA) is presented as an efficient actuator for legged locomotion. The CV-SEA implements a continuously-variable transmission (CVT) between a motor and series elastic element ...

Piezoelectric Actuators for Tactile and Elasticity Sensing [PDF]
Actuators, 2020 Piezoelectric actuators have achieved remarkable progress in many fields, being able to generate forces or displacements to perform scanning, tuning, manipulating, tactile sensing or delivering functions. In this work, two piezoelectric PZT (lead zirconate titanate) bimorph actuators, with different tip contact materials, were applied as tactile ...
