Wireless SensorSystem with Bidirectional Communications
The system contains units: wireless, control, actuator, software equipment. RF wireless unit ensures wireless communication between control unit and sensors as well as wireless switch unit. The control unit controls system operation, i.e. communication transfer, [...]
Innovative Gas Sensors for Sub-ppm Detection of Organophosphorus Nerve Agents by Chemically Functionalized Carbon Nanotube Field-Effect Transistors
In this communication, we will present innovative sensors based on carbon nanotube field-effect transistors (CNT-FET) for detection of organophosphorus agents (OP, Sarin-like molecules). We have functionalized CNT with organic moieties reactive towards OPs that form [...]
Nano-porous poly-silicon gated ion selective field effect transistors
We report the realization of ultra high sensitivity ion-selective field effect transistors (ISFET) devices by means of a nano-porous silicon structures placed on the gate region. Thanks to the presence of a nano-porous polysilicon film [...]
A Fully Symmetric and Completly Decoupled MEMS-SOI Gyroscope
Sharaf A., Sedky S., Serry M., Elshurafa A., Ashour M., Habib S.E.-D., American University in Cairo, EG
Gyroscopes are sensors that measure rotation rate and are extremely important in many applications such as navigation and vehicle stability control. Despite being manufactured in many technologies in various shapes and sizes, micro-electromechanical (MEMS) gyroscopes [...]
Flexible Micropost Arrays For Studying Traction Forces Of Vascular Smooth Muscle Cells
This paper describes the design, modeling, fabrication and characterization of micromachined arrays of high density 3-dimensional microposts fabricated using flexible silicone elastomers for studying traction forces generated by vascular smooth muscle cell. It also reports [...]
Individually addressable Cantilever Arrays for Parallel Atomic Force Microscopy
Cantilever arrays probes with self-sensing and self-actuating cantilevers and integrated sharp silicon tips for parallel surface scanning were realized. Each cantilever is equipped with a piezoresistive deflection sensor and a thermal bimorph actuator enabling an [...]
Triaxial Accelerometer for Placement Inside the Ear Canal
A second generation MEMS-based in-ear shock measurement system fitting deep into the ear canal has been developed to measure traumatic brain injury (TBI). It consists of the world’s smallest triaxial accelerometer die, a shielded flex [...]
Nanolab System for Nanoelectronics and Sensors
This project idea is the implementation of a complete and general system for the realization of nanodevices based on nanogaps (small gaps in a gold wire) exploited with a feedback controlled circuit. The system, built [...]
