Innovative approach to high stroke electrostatic actuators
, 2022 Paper 86160TThe electrostatic actuation is still a preferred principle in modern microelectromechanical systems (MEMS). Based on the Coulomb attraction between two different point charges, the electrostatic actuation is a surface effect and thus volume ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells
Advanced Materials, EarlyView.This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Analysis of small scale electrostatic linear actuation
, 2018 The use of electrostatic forces for millimeter-scaled linear actuation is explored through simulated application. Typically used in MEMs, the increased scaling in size of electrostatic devices leads to diminishing accelerations for actuation, as the ...

Electrostatic in-plane structural superlubric actuator
Nature CommunicationsMicro actuators are widely used in NEMS/MEMS for control and sensing. However, most are designed with suspended beams anchored at fixed points, causing two main issues: restricted actuated stroke and movement modes, and reduced lifespan due to fatigue from repeated beam deformation, contact wear and stiction.
