Modeling and Experimental Evaluation of Haptic Localization Using Electrostatic Vibration Actuators

open access: yesIEEE Access, 2023
Touch screen devices have become ubiquitous in modern day-to-day lives. While smaller touchscreen devices provide enough user engagement with meaningful haptic feedback, large touch devices still lack meaningful haptic stimulation.

A three million Q factor tuning fork resonator based on a vibration isolation structure

open access: yesAIP Advances, 2022
The quality factor (Q factor) is one of the most important parameters for a resonant sensor since it determines the performance of the resonant system. The mass distribution imbalance caused by the fabrication error has a great impact on the anchor loss,

Linear and Nonlinear Electrostatic Excitations and Their Stability in a Nonextensive Anisotropic Magnetoplasma [PDF]

open access: yesSymmetry, 2021
In the present work, the propagation of (non)linear electrostatic waves is reported in a normal (electron–ion) magnetoplasma. The inertialess electrons follow a non-extensive q-distribution, while the positive inertial ions are assumed to be warm mobile.

Dual Excitation Electrostatic Stepping Motor.

open access: yesIEEJ Transactions on Industry Applications, 1996
Electrostatic motors have been believed to be weaker than electromagnetic motors which are typically used for mechatronic devices. However, electrostatic motors are preferable to electromagnetic ones for micro mechanical applications since their force per volume ratios increase as their dimensions are reduced. This follows that a large output should be
