Weareworking towardactualizing a real-time3D modeling system. This modeling system uses a sensor network that distributesmany 1mm-class sensor nodes in plastic clay. The distributed sensors sense the distances between them, and the sensor network collects the node-to-node distance information to recognize the clay shape by calculating the relative positions of the nodes. This paper proposes a d...

Modern sliding table saws are equipped with several passive safety devices. However, alone in Germany several hundred severe injuries or limb amputations occur each year due disregarding safety regulations and demounting of passive safety devices. Thus an active safety system is developed in order to protect the machine user. For this purpose, a multi sensor system for hazard analysis based on ...

This paper presents a measurement technique and system for the contactless interrogation of capacitive sensors via electromagnetic coupling. The interrogation unit employs a primary coil to periodically excite the capacitive sensor connected to a secondary coil forming an LC resonant circuit. When the excitation to the primary coil is switched off the damped response of the LC circuit is detect...

In this paper, parameters related to the sensitivity of the interface circuits for capacitive sensors are determined. Both the input referred noise and capacitance of the input transistors are important for capacitive sensitivity. Chopping is an effective technique for signal conditioning circuits because of its capability of reducing circuit noise at low frequencies. The capacitive sensitivity...

This work presents the design and implementation of a porous polydimethylsiloxane (PDMS)-based wide-range flexible pressure sensor for autonomous underwater vehicles. The capacitive sensor, with PDMS as dielectric, is encapsulated in bulk polymer. fabricated was evaluated over wide range (0-230 kPa), which similar to pressures experienced up approx. 23 m below sea level. sensors showed linear r...

The development of an electronic skin is critical to the realization of artificial intelligence that comes into direct contact with humans, and to biomedical applications such as prosthetic skin. To mimic the tactile sensing properties of natural skin, large arrays of pixel pressure sensors on a flexible and stretchable substrate are required. We demonstrate flexible, capacitive pressure sensor...
