A low-cost pH Sensor Based on RuO2 Resistor Material

Fresh water deficiency caused by climate change calls for employing novel measures to ensure safety of drinking water supply. Wireless sensor networks can be used for monitoring hydrological conditions across wide area, allowing flow forecasting and early detection of pollutants. While there are no fundamental technological obstacles to implementation of large area sensor networks, their feasib...

On-Line, Low-Cost and Pc-Based Fingerprint Verification System Based on Solid- State Capacitance Sensor

With the recent advancements in the sensor technology and solid-state VLSI design the new capacitance fingerprint sensor can be miniaturized. The Automatic Gain Control (AGC) adjusts the acquired images to produce highest quality images over different dryness, wet and dirty conditions. We developed a low-cost, on-line, and Pc-based fingerprint verification system. The system performance is high...

Commercial Motion Sensor Based Low-Cost and Convenient Interactive Treadmill †

Interactive treadmills were developed to improve the simulation of overground walking when compared to conventional treadmills. However, currently available interactive treadmills are expensive and inconvenient, which limits their use. We propose a low-cost and convenient version of the interactive treadmill that does not require expensive equipment and a complicated setup. As a substitute for ...

Couple Stress Effect on Micro/Nanocantilever-based Capacitive Gas Sensor

Micro/nanocantilevers have been employed as sensors in many applications including chemical and biosensing. Due to their high sensitivity and potential for scalability, miniature sensing systems are in wide use and will likely become more prevalent in micro/nano-electromechanical systems (M-NEMSs). This paper is mainly focused on the use of sensing systems that employ micro/nano-size cantilever...
