A flexible pressure sensor with a linear response over wide range high sensitivity is extremely desirable for high-pressure applications, such as monitoring body weight and plantar distributions. As promising candidate to achieve the sensitivity, porous structure in capacitive sensors essential. However, this invokes early saturation of owing low compression modulus. In study, thermoplastic mic...

Surface micromachining has become an established technology for inertial sensing. Compatibility with standard IC fabrication processes enables monolithic integration of the sensing element and interface electronics for reduced size and power dissipation, simplified packaging, and increased functionality. The need to resolve sub-Angstrom displacements poses a challenge on the interface. Capaciti...

This paper presents an inkjet printing capacitive microwave sensor for toxic vapor detection. The designed sensors were presented and fabricated with success. The experiments show sensitivity to ethanol vapor according to the S parameters. It is equal to 0.9 kHz/ppm and 1.3 kHz/ppm for the sensors based on 5 and 50 sensitive layers respectively. This sensor will be integrated into real-time mul...

A high-temperature pressure sensor realized by the post-fire metallization on zirconia ceramic is presented. The pressure signal can be read out wirelessly through the magnetic coupling between the reader antenna and the sensor due to that the sensor is equivalent to an inductive-capacitive (LC) resonance circuit which has a pressure-sensitive resonance frequency. Considering the excellent mech...

Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...

This research presents a case study of production monitoring on an aerospace composite component: the hinge arm of the droop nose mechanism on the Airbus A380 wing leading edge. A sensor network composed of Fibre Bragg Gratings, capacitive sensors for cure monitoring and thermocouples was embedded in its fibre reinforced lay-up and measurements were acquired throughout its Resin Transfer Mouldi...

In this paper, we present the design, fabrication and test of a batch fabricated capacitive pressure sensor with an integrated Guyton capsule for interstitial fluid pressure measurement. The sensor is composed of 12 μm thick single crystalline silicon membrane and a 3 μm gap, hermetically sealed through silicon–glass anodic bonding. A novel batch scale method for creating electrical feed-throug...

Highly sensitive capacitive pressure sensors with wide detection range are needed for applications such as human-machine interfaces, electronic skin in robotics, and health monitoring. However, it is challenging to achieve high sensitivity at the same time. Herein, we present an innovative approach obtain a highly sensor by introducing zinc oxide nanowire (ZnO NW) interlayer polydimethylsiloxan...
