Design and Analysis of MEMS based Piezoelectric Accelerometer Having Square Shaped Proof Mass
Abstract: In any spacecraft launching program, the most prominent issue is to locate the spacecraft or satellite, in particular orbit of any particular planet. Now, while making the position of that spacecraft in space, abrupt changes in velocity occur and these velocity changes can break the controlling circuitry of the system since the velocity changes occur at very high environmental pressure. The designed device converts the deflections due to mentioned pressure …

Design and Simulation of MEMS-based Piezoelectric Accelerometer
Abstract: In this work, the modelling and design of a Micro Electro Mechanical Systems (MEMS) uniaxial accelerometer has been presented. The design of the sensor includes sensing acceleration in the x-direction only. The device achieves this function using a proof mass suspended through four spring structure. The device dimensions are finalized mathematically and the simulated using Finite Element Analysis. The structure is simulated with and without piezoelectric material ZnO and a …

Design of Feedback Loop for Ultra-sensitive Nano-g Resolution MEMS Tunneling Accelerometer
Abstract: The tunneling accelerometer often used for attitude control of micro and nano satellite can be operated both in open loop circuit as well as close loop circuit. Closed-loop operation improves the overall sensor linearity, dynamic range, and bandwidth. The interface circuitry in a closed-loop device reads the sensor signal and uses feedback to maintain the proof mass in a null position in a stable manner. In this paper we present …

Health Monitoring for COVID-19 Similar Disease Using Wearable Device
Abstract: Due to the massive spike in uncertainties triggered by the COVID-19 disease, many countries strategies to reduce the spread by contact tracing. Currently governments around the world battling against pandemic and digital tools are implemented to augment and accelerate contact tracing. Indian government authorities are heavily depending on Aarogya setu App to detect potentially infected population, but second waves showed us that this system is not full proof. Also, there …
