Blood Pressure Sensors: Materials, Fabrication Methods, Performance Evaluations and Future Perspectives

Review of Electromagnetic-Based Crack Sensors for Metallic Materials (Recent Research and Future Perspectives)

Evaluation and non-destructive identification of stress-induced cracks or failures in metals is a vital problem in many sensitive environments, including transportation (steel railway tracks, bridges, car wheels, etc.), power plants (steam generator tubing, etc.) and aerospace transportation (landing gear, aircraft fuselages, etc.). There are many traditional non-destructive detection and evalu...

Oxygen sensors: Materials, methods, designs and applications

Advancement of gas sensor technology over the past few decades has led to significant progress in pollution control and thereby, to environmental protection. An excellent example is the control of automobile exhaust emissions, made possible by the use of oxygen gas sensors. Since early 1970’s there have been sustained studies on oxygen sensors and has led to development of sensors for various a...

Persian-Speaking Teachers’ Perspectives on Methods and Materials for Teaching English as an International Language

Despite the global spread of English, it seems that voices from Persian-speaking teachers concerning English as an international language (EIL) teaching methods and materials are underrepresented. The present study set out to explore how nonnative Persian-speaking English language teachers respond to the increasing global dominance of EIL and native- and non-native-speakers’ language norms with...

Membrane Engineering: Future Perspectives

A Short Review on Fabrication Methods of Micro-Cantilever for Ionic Electroactive Polymer Sensors/Actuators

   Micro-electroactive polymers have wide applications from industry to healthcare. Artificial muscles, microvalves, microswitches, haptic sensing, blood pressure and pulse monitoring are some potential applications for micro-electroactive polymers. The most advantage of micro-electroactive polymers as sensors and actuators is bio-compatibility and low power threshold for large deformations...
