Differential Pressure Transducer for Corrosion Monitoring of Iron

A Pitch-Catch Based Online Structural Health Monitoring of Pressure Vessels, Considering Corrosion Formation

Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in pro...

Design and Evaluation of a Pressure and Temperature Monitoring System for Pressure Ulcer Prevention

Introduction Pressure ulcers are tissue damages resulting from blood flow restriction, which occurs when the tissue is exposed to high pressure for a long period of time. These painful sores are common in patients and elderly, who spend extended periods of time in bed or wheelchair. In this study, a continuous pressure and temperature monitoring system was developed for pressure ulcer preventio...

Subnanowatt Microbubble Pressure Transducer

We present the first all-Parylene microbubble pressure transducer (μBPT). The μBPT utilizes an electrolytically generated microbubble (μB), trapped in a Parylene microchamber, for pressure sensing. Pressure-induced bubble size variation is detected by electrochemical impedance measurement. Real-time hydrostatic pressure measurement with excellent sensitivity (-10.7 Ω/psi, ±0.1 psi) up to 1.8 ps...

Virtual Techniques for Liquid Level Monitoring Using Differential Pressure Sensors

The purpose of presented paper is to demonstrate an innovative approach for low cost continuous liquid level monitoring based on virtual instrumentation. Most of the traditional measuring systems were designed and implemented by complicated hardware circuitry. It made the product expensive, with low functionality and with limited precision. With virtual measurement technology, more of the instr...
