Graphene-Paper Pressure Sensor for Detecting Human Motions

In this paper, a graphene-paper pressure sensor that shows excellent performance in the range of 0-20 kPa is proposed. Compared to most reported graphene pressure sensors, this work realizes the optimization of sensitivity and working range, which is especially suitable for wearable applications. We also demonstrate that the pressure sensor can be applied in pulse detection, respiratory ...

Pressure Sensor Research Paper |

Pressure Sensor Research Paper. 1498 Words 6 Pages. Pressure Sensor A pressure sensor also known as pressure transducer is used to measure pressure typically of gases or liquids. It converts pressure into an analog electrical signal such as a voltage output or current output which can easily be measured. Pressure sensors either convert the pressure into mechanical movement or …

A wearable and highly sensitive pressure sensor with ...

Here we report an efficient, low-cost fabrication strategy to construct a highly sensitive, flexible pressure sensor by sandwiching ultrathin gold nanowire-impregnated tissue paper between two thin polydimethylsiloxane sheets. The entire device fabrication process is scalable, enabling facile large-area integration and patterning for mapping spatial pressure distribution. Our gold nanowires ...

Paper-based piezoresistive MEMS sensors

The working principle on which these paper-based sensors are based is the piezoresistive effect generated by conductive materials patterned on a paper substrate. The device is inexpensive (~$/device for materials), simple to fabricate, light weight, and disposable. Paper can be readily folded into three-dimensional structures to increase the stiffness of the sensor while keeping it light ...

DESIGN AND DEVELOPMENT OF HALL EFFECT BASED PRESSURE ...

circuit with Bourdon tube as a pressure sensor is reported by Bera et al . [5] with a resolution of 5 psig in the range of 0-45 psig. The advantage of the circuit is large sensitivity, but it decreases with the signal- to-noise ratio of the circuit. In another work proposed by Bakhoum and Marvin[6], an ultrahigh-sensitivity pressure and vibration sensor is designed. In this paper hall probe ...

Fabrication of highly sensitive capacitive pressure ...

· The pressure sensor using a porous PDMS dielectric layer fabricated with 40 wt% sacrificial solvent had a sensitivity of kPa −1, which is 11 times higher than that of the sensor using a non-porous dielectric layer. To further improve the sensitivity, low-cost commercial glass was used as a mold to form microstructures on the surface of the porous dielectric layer. Due to the enhanced ...
