Advanced Materials Technologies, EarlyView.A custom shape memory polymer material selection process relates quantitative application criteria (e.g., compression garment yarns) to material characterization information. The selected materials are manufactured into yarn geometries, which expand the design space by creating structural stress‐strain profiles beyond the nominal material stress‐strain

Electrostatic Layer Jamming Variable Stiffness for Soft Robotics
IEEE/ASME Transactions on Mechatronics, 2019 A novel layer jamming variable stiffness technique for soft robotics is proposed in this paper, which we call electrostatic layer jamming (ELJ). The basic principle of the ELJ is using electrostatic attraction to squeeze material layers to generate friction and then engage jamming.

Electrostatic-Capacitive MEMS Stiffness Sensor with Position-Feedback Mechanism
2021 IEEE Sensors, 2021 A Micro Electro-Mechanical System (MEMS) stiffness sensor based on position-feedback mechanism which integrates a capacitive position sensor and a variable-area electrostatic actuator mechanically connected to a movable probe tip is presented. A closed-loop mechanism allows to electrically set the working position of the probe tip and to measure the ...

A resonant micro accelerometer based on electrostatic stiffness variation
Meccanica, 2013 A new out-of-plane resonant micro-machined accelerometer has been designed, modelled and fabricated. The sensing principle is based on the variation of the electrostatic stiffness of two torsional resonators mechanically coupled with an inertial proof mass.

Stiffness Measurement of Micro-Cantilever Based on Negative Electrostatic Stiffness
Nanoscience and Nanotechnology Letters, 2020Micro-cantilever is basic structure of Micro-Electro-Mechanical-Systems (MEMS) sensor, and mechanical stiffness is the most important parameter of micro-cantilever. The mechanical stiffness can be affected by shape, size and material, and it should be experimentally measured for fabrication variation.

A variable stiffness dielectric elastomer actuator based on electrostatic chucking
Soft Matter, 2017 Dielectric elastomer actuators (DEA) are one type of promising artificial muscle; however, applications of bending-type DEA for robotic end-effectors may be limited by their low stiffness and ability to resist external loads without buckling. Unimorph DEA can produce large out-of-plane deformation suitable for use as robotic end effectors; however ...

Out-of-plane electrostatic microactuators with tunable stiffness
2010 IEEE 23rd International Conference on Micro Electro Mechanical Systems (MEMS), 2010 This paper reports on the development of out-of-plane electrostatic microactuators whose stiffness can be actively tuned through an integrated mechanism based on in-plane forces acting on bending flexures. The devices combine out-of-plane flexures and drives with in-plane flexures and electrodes.
