The ambient vibrations can be of great promise for harvesting energy initially at small scale to use for micro and nano scale devices. Such vibrations converted to electrical energy by piezoelectric transducer due to their major significance. Various research journals have introduced the phenomenon of energy optimization to increase the generated power and used directly for application like ...

Different configurations of MEMS based accelerometer has been made and analysed using COMSOL Multiphysics. The designs presented in this paper consist of a square shaped proof mass with flexures supporting it. Different position and varied number of supporting flexures attached to the proof mass makes each configuration distinct. The piezoresistors are placed near the proof mass and frame ends ...

Electrical scanning probe microscopy (SPM) techniques, such as electrostatic force microscopy, nanoscale impedance microscopy or scanning near field microwave microscopy, are a relatively new branch of microscopy techniques that can generate images of the nanoscale electrical properties of samples (conductivity, permittivity, charge, etc.). These techniques scan the surface of a sample ...

The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT (piezoelectric material), Platinum (electrodes) and Zirconium Oxide as the buffer layer for the PZT film and polyimide ...

Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be generated by application of a voltage to an IDT deposited on the surface of a piezoelectric substrate. The ...
