Overload pressure sensor can be used to measure and control the pressure of the high pressure compressed air and gas. In this paper, under the premise of ensuring the sensor full-scale range of linear response, through the appropriate contact of the flexible diaphragm and the substrate to effectively improve the sensor overload. Overload pressure sensor has a housing, metal pressure port as wel...

This paper presents the development of a tactile sensor based on pressure sensitive conductive rubber and outlines the resistance measurements performance. This sensor is specially designed for a robotic hand developed at UiTM Faculty of Mechanical Engineering. It exhibits piezoresistive like behaviour whose resistance change with force/pressure enables its applications as tactile sensor. The o...

In this study, polydimethylsiloxane (PDMS) and conductive carbon nanoparticles were combined to fabricate a conductive elastomer PDMS (CPDMS). A high sensitive and flexible CPDMS strain sensor is fabricated by using stamping-process based micro patterning. Compared with conventional sensors, flexible strain sensors are more suitable for medical applications but are usually fabricated by photoli...

This paper presents a piezoresistive pressure sensor with a shield layer for improved stability. Compared with the conventional piezoresistive pressure sensors, the new one reported in this paper has an n-type shield layer that covers p-type piezoresistors. This shield layer aims to minimize the impact of electrical field and reduce the temperature sensitivity of piezoresistors. The proposed se...

This paper reports a microelectromechanical systems (MEMS) resonant varifocal mirror integrated with piezoresistive focus sensor. The varifocal mirror is driven electrostatically at a resonant frequency of a mirror plate to obtain the wide scanning range of a focal length. A piezoresistor is used to monitor the focal length of the varifocal mirror. The device is made of a silicon-on-insulator (...
