Fully-printed stretchable pressure sensor arrays

In this paper we present elastomeric large-area arrays of pressure sensors based on printed electronics. Two applications are presented to demonstrate the versatility and scalability of the presented technology. The first consists of a shoe inlay with over 700 sensors (5 mm pitch) and the second consists of large-area sensor mat (30 cm × 40 cm)...

Parametric Nonlinear Regression Models for Dike Monitoring Systems

Dike monitoring is crucial for protection against flooding disasters, an especially important topic in low countries, such as the Netherlands where many regions are below sea level. Recently, there has been growing interest in extending traditional dike monitoring by means of a sensor network. This paper presents a case study of a set of pore...

SOI based mechano-optical pressure sensor using a folded micro ring resonator

A compact, mass producible Silicon On Insulator (SOI) based pressure sensor consisting of a folded Micro Ring Resonator (MRR) on a circular diaphragm is successfully designed, fabricated and characterized. An application of pressure deflects the diaphragm, causing stress in the MRR, which elongates the waveguide length and changes the effective...

Silicon on insulator photonic integrated sensors: On-chip sensing and interrogation

In this paper, we present two examples of photonic sensors based on ring resonators in Silicon-on-Insulator (SOI) waveguide technology as mass production compatible sensing units for the measurement of: strain, and ultrasound. Furthermore, the sensing units are characterized in extreme conditions to validate their robustness in harsh industrial...

Capacitive pressure sensor in post-processing on LTCC substrates

A capacitive pressure sensor was realized by means of a post-processing step on a low temperature co-fired ceramics (LTCC) substrate. The new sensor fabrication technology allows for integration of the sensor with interface circuitry and possibly also wireless transmission circuits on LTCC substrates to realize a truly autonomous sensor unit. A...

Computer assisted design study of a low-cost pressure sensor

The application of numerical techniques for the design of a low cost pressure sensor is described. The numerical techniques assist in addressing issues related to the thermo-mechanical performance of the sensor. This comprises the selection of the materials and dimensions used for the sensor itself and the substrate on which it is mounted....
