Electric field sensing characteristics of ZnO/SiO ₂ /Si surface acoustic wave devices

Journal of Micromechanics and Microengineering, 2022
Abstract Existing microelectro mechanical systems (MEMSs) electric field sensors have movable parts and electronic components. The movable parts are susceptible to external vibration, and the electronic components distort the distribution of the measured electric field. Therefore, we proposed a novel MEMS electric

Graphite oxide multilayers for device fabrication: Enzyme‐based electrical sensing of glucose

physica status solidi (a), 2015
In this paper, the use of graphite oxide multilayers as a transducer material for the fabrication of electronic devices is outlined. Graphite oxide flakes were produced in a solution‐based exfoliation method optimized for large area thin layers with narrow size distribution.

The Oxford Optical Pointer: a direction-sensing device with proportional electrical output

Medical & Biological Engineering & Computing, 1988
For some disabled people pointing provides a more convenient means of communication and control than the use of switches. The quadriplegic who retains good control of head movement can be provided with a number of input alternatives, but no existing system meets all the requirements of a general-purpose electronic pointing device.

Electrical behavior of devices composed by dielectrophoretically deposited carbon nanotubes for gas sensing applications

2014 29th Symposium on Microelectronics Technology and Devices (SBMicro), 2014
Miniaturized gas sensors have been developed with a view to integrating them into smart systems for environment control, for example. Intensive research has been focused on investigating new sensing materials, such as carbon nanotubes (CNT) because of their promising characteristics, but there are challenges related to their application in commercial ...

RFID helix antenna on power cord for the sensing of home electrical devices activity

2017 11th European Conference on Antennas and Propagation (EUCAP), 2017
A flexible RFID-Helix antenna wrapped around the power-cord, integrated with a RFID tag and a current impulse detection circuit, for wireless sensing of the activity of home electrical devices, is proposed. While the use of a straight dipole showed a significant distortion of the antenna radiation pattern due to the very close proximity of the wires ...

Electrical characterization of ethanol sensing device based on Vanadium oxide/Porous Si/Si structure

Solid State Ionics, 2013
Abstract A gas sensing device based on Vanadium oxide (V2O5)/Porous Si (PS)/Si structure has been used to detect ethanol vapor at different concentrations. The V2O5 thin films were deposited on porous silicon by sol-gel (Dip-coating) technique. The Vanadium oxide has been produced from vanadium alcoxide precursor.

Velocity Measurement with Electrical Double-Sensing Devices in Two-Phase Flow

1984
A computer-aided-data-processing method was developed to enable the velocity and liquid holdup measurements of liquid lumps having a wide range of velocities from forward and backward flow. Furthermore, an algorithm for the development of a relatively simple microprocessor was produced with aiming the measurement of forward flow.

RFID Tag Coupled with a Magnetic Sensor for Wireless Sensing of Home Electrical Devices

2018 48th European Microwave Conference (EuMC), 2018
A novel solution for sensing the activity of different electrical devices connected to the home power line, based on the use of a long-range UHF RFID system, is proposed. The solution uses a 3-axis magnetometer, coupled with a flexible RFID tag wrapped around the power cord of an electrical device to be sensed.

Aircraft Multi-Bus Electrical System Using a Hall-Effect Sensing Device

SAE Technical Paper Series, 1981
<div class="htmlview paragraph">The multi-bus electrical system, using a Hall-effect sensing device, is designed to meet FAR requirements. The system allows the automatic separation of a faulted bus through the use of the Hall-effect device. Should the loss of both generators occur, the battery will automatically become isolated from the loads ...

A device for sensing and balance augmentation using functional electrical stimulation

2020
Based on World Health Organization (WHO) report, between 250,000 and 500,000 people suffer from disabilities caused by spinal cord injuries each year. The result of this study is development of a medical device to restore walking in such patients using Functional Electrical Stimulation (FES). We selected dogs as our animal subject. This device uses FES
