A Hybrid Thermopneumatic and Electrostatic Microvalve with Integrated Position Sensing
This paper presents a low-power hybrid thermopneumatic microvalve with an electrostatic hold and integrated valve plate position sensing. This combination of actuators in a single structure enables a high throw and force actuator with low energy ...

Scanning and Actuation Techniques for Cantilever-Based Fiber Optic Endoscopic Scanners—A Review
Endoscopes are used routinely in modern medicine for in-vivo imaging of luminal organs. Technical advances in the micro-electro-mechanical system (MEMS) and optical fields have enabled the further miniaturization of endoscopes, resulting in the ability ...

Multimode Hydraulically Amplified Electrostatic Actuators for Wearable Haptics
The sense of touch is underused in today’s virtual reality systems due to lack of wearable, soft, mm‐scale transducers to generate dynamic mechanical stimulus on the skin.

Dynamics of Microbeams under Multi-Frequency Excitations
This paper presents an investigation of the dynamics of microbeams under multiple harmonic electrostatic excitation frequencies. First, the response of a cantilever microbeam to two alternating current (AC) source excitation is examined.

Kinesin as an Electrostatic Machine [PDF]
Kinesin and related motor proteins utilize ATP fuel to propel themselves along the external surface of microtubules in a processive and directional fashion. We show that the observed step-like motion is possible through time varying charge distributions furnished by the ATP hydrolysis circle while the static charge configuration on the microtuble ...

Visualizing electrostatic gating effects in two-dimensional heterostructures [PDF]
The ability to directly monitor the states of electrons in modern field-effect devices—for example, imaging local changes in the electrical potential, Fermi level and band structure as a gate voltage is applied—could transform our understanding of the ...

Condenser microphone with small size and high sensitivity Using a circular diaphragm with fixed center [PDF]
In this paper, a new single-chip MEMS capacitor microphone on a silicon wafer by minimizing the size and the reduction of mechanical strength using a circular diaphragm with a fixed center is proposed. In the proposed microphone, the diaphragm includes a
