MEMS(Microelectromechanical systems) based energy harvesting is process of extracting energy from natural resources in small amounts. Here, number of (millions) small energy harvesting modules lead to substancial energy. In this design, a piezoelectric material is used to scavenge ... Per saperne di più
Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... Per saperne di più
3D model of MEMS based SAW gas sensor is designed using Focused Inter Digital Transducers design. Surface displacement & Electrical potential are analyzed at resonance & anti-resonance frequencies. Operating frequency is from 8.7 MHz which acts as start band and 9.2 MHz as stop ... Per saperne di più
Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing ... Per saperne di più
The role of stretchable electronics systems allows the design of new reconfigurable macro-electronics, that extends a device capability to function as a distributed sensor network which can potentially be used for wearable electronics. At the moment such devices are primarily based on ... Per saperne di più
In this contribution we present a COMSOL Multiphysics® example of a disk piezoelectric ceramic transformer (D-PT) coupled with a bipolar NPN transistor to form an auto-oscillator. The comparison between the simulations and the measurements made on our prototype are found to be in good ... Per saperne di più
This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis ... Per saperne di più
The focus of this paper is to study the effect on resonance frequency and power enhancement techniques[1] of piezoelectric MEMS and modeling, design, and optimization of a piezoelectric generator based on a two-layer bending element(Figure 1) using COMSOL Multiphysics.
