Embedding piezoelectric nanowires within a soft elastomer material should provide superior pressure sensing transducer, exploiting the properties of nanowire while maintaining flexibility. Here, flexible sensor has been fabricated on Kapton substrate and incorporated layer polydimethylsiloxane with embedded zinc oxide as mechanism. In response to applied compressive up 127 kPa, device generated...

In this paper, we experimentally demonstrated the fabrication and hydrostatic pressure characteristics of a twin-core photonic crystal fiber (TC-PCF). Mode couplings in the TC-PCF for x- and y-polarizations were analyzed simultaneously using group effective index of guiding modes. The output spectrum of the TC-PCF was modulated due to the combined couplings of the two polarizations. To the best...

Reliable hermetic packaging of microelectromechanical system (MEMS) pressure sensor arrays for underwater applications always presents a formidable challenge, which is further compounded by the unforgiving harsh sea environments, during the design, fabrication and characterization stages of the sensor arrays. As such, a flexible underwater diaphragm-based pressure sensor array packaging scheme ...

In the present study, we propose and develop a flexible pressure sensor based on the piezoresistive effect of multilayer graphene films on polyester textile. The pressure response results from the deformation of graphene conductive network structure and the changes in resistance. Here, we show that the graphene pressure sensor can achieve a sensitivity value of 0.012 kPa - 1 , the measurement r...

In the field of photoelectric sensing and measurement, laser triangulation is a superior and widely used technology due to its advantages of high accuracy, rapidity, and non-contact. This paper first applied it to the measurement of pressure, and proposed and designed a laser-type pressure sensor. The sensor measured the center deflection of the circular pressure-sensitive diaphragm using the l...
