چکیده

This paper reports the design, fabrication and testing of a free-standing encastre beam resonator which is entirely fabricated using screen printing onto a flexible polyimide substrate. The design of the free-standing resonator was achieved using sacrificial techniques. The resonator was designed to be excited at one end of the beam and the vibrations detected on the other end using piezoelectric material. The resonator was 11mm long and 4mm wide with an air gap of 119μm, created by selectively removing the sacrificial layer. The device resonates in air with maximum amplitude of 0.1545 volt at fundamental frequency of 3.834 kHz. © 2014 The Authors. Published by Elsevier Ltd. Peer-review under responsibility of the scientific committee of Eurosensors 2014.

Design and performance analysis of a seismic grade resonance nano accelerometer

In this paper, design and performance analysis of a resonance nanosensor for earthquake low frequency geoacoustic waves detection is proposed. The model comprises of a proof mass suspended to the substrate, and a nanobeam attached to the intersection of the proof mass to the substrate. The nanobeam could be cosidered as a clamped-clamped nanoresonator actuated electrostartically. The induced ac...

A New Sensor Based on Graphite Screen Printed Electrode Modified With Cu-Nanocomplex for Determination of Paracetamol

Paracetamol is a non-steroidal anti-inflammatory drug used as an antipyretic agent for the alternative to aspirin. Conversely, the overdoses of paracetamol can cause hepatic toxicity and kidney damage. Hence, the determination of paracetamol receives much more attention in biological samples and also in pharmaceutical formulations. Here, we report a rapid<span id="transmark" style="display: non...
