[1] Naval Physical and Oceanographic Laboratory, Kochi, Kerala, India
[2] Govt. Model Engineering College, Kochi, Kerala, India

Hydrophones are acoustic receivers, which can be used to listen to the sound propagating underwater for the purposes of monitoring marine life, or other sound producing activities in the sea. Commonly used hydrophones are based on piezoelectric transducers. With the introduction of fiber ... Mehr lesen

Numerical Study on Shear Horizontal Electromagnetic Acoustic Transducers for Generation of Ultrasonic Guided Waves for Absorber Tubes used in Concentrated Solar Plants

L. Cheng[1], A. Mohimi[1], M. Kogia[1], V. Kappatos[1], C. Selcuk[1], T.-H. Gan[1]
[1]Brunel Innovation Centre, Brunel University, Uxbridge, UK

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential ... Mehr lesen

Thermoviscous Acoustics – Piezoelectric Modeling and Simulation of Surface Acoustic Wave Devices

V. M. Dhagat [1], P. Dufilie [2],
[1] University of Connecticut, Mansfield, CT, USA
[2] Phonon Corporation, Simsbury, CT, USA

New drug discovery and development is costly; of all compounds investigated for use in humans, only a small fraction is approved for treatments around the world. The pharmaceutical industry has started switching from molecular drugs to protein-based drugs due to high specificity, ... Mehr lesen

Simulation of a New PZT Energy Harvester with a Lower Resonance Frequency Using COMSOL Multiphysics®

H. Elbahr[1], T. Ali[1,2], A. Badawi[1], S. Sedky[1]
[1]Zewail City of Science and Technology - Cairo, Cairo, Egypt
[2]Cairo University, Cairo, Egypt

Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low ... Mehr lesen

Simulation of a Tether Structure for Ultra-stretchable Monolithic Silicon Fabric

[1] Computer, Electrical, & Mathematical Sciences & Engineering, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2] The University of British Columbia, School of Engineering, Vancouver, BC, Canada

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 ... Mehr lesen

Parameter Extraction and Support-Loss in MEMS Resonators

Peter Steeneken
Project Leader
RF MEMS Research Group
NXP Semiconductors
Eindhoven, The Netherlands

In this paper it is shown how the equivalent circuit parameters of a MEMS resonator can be simply obtained from an eigenfrequency simulation. Additionally, it is demonstrated that the Q-factor as a result of support losses in a MEMS resonator can be determined using a matched boundary ... Mehr lesen
