This paper describes an innovative sensor system which can detect and track people in a room by means of an array of capacitive sensors beneath the floor covering. By combining cutting-edge technology from the domains of capacitive sensing, wireless data transmission, interconnecting technology between textiles and microelectronics and high level data processing it is possible to support variou...

The use of capacitive-mesh output couplers for optically pumped far-infrared molecular lasers has been extended throughout the far-infrared spectrum, between 42 microm and 1.2 mm, and the optimum grid constants have been found for several lines. At shorter wavelengths, performance has been improved by the use of a novel hybrid capacitive-mesh hole output coupler.

Chip-to-chip interconnection, based on wireless communication by capacitive coupling was investigated. This innovative approach will considerably reduce the pitch of the pin and strongly help in the implementation of a dense network of interconnects, while improving inter-chip bandwidth and power dissipation. The 3D integration technology based on aligned wafer-to-wafer direct bonding technique...

The signal-to-noise ratio (SNR) and driving levels of capacitive touch sensors determine the applicability of these sensors to thinner displays and sensor-integrated modules. The simultaneous driving technique has been widely applied to capacitive touch sensors to cope with various types of environmental noise. A Hadamard matrix has been used to determine the driving code and multiplex capaciti...

Inductive magnetic probes are often used to measure oscillating magnetic fields in plasma.r3 The sensitivity of a magnetic probe to electrostatic potentials (“capacitive pickup”) is usually an important consideration. Centertapped construction of such a probe, shown in Fig. 1 (b), helps to minimize capacitive pickup with respect to a simply wound probe [Fig. 1 (a)]. This relies on the fact that...

To obtain maximum unobtrusiveness with sensors for monitoring health parameters on the human body, two technical solutions are combined. First we propose contactless sensors for capacitive electromyography measurements. Secondly, the sensors are integrated into textile, so complete fusion with a wearable garment is enabled. We are presenting the first successful measurements with such sensors. ...

Capacitive accelerometers [1] have advantages such as zero static bias current, the capability of high sensitivity, and excellent thermal stability, making their use in low-power applications attractive. In this paper, an interface ASIC designed for a capacitive 3-axis micro-accelerometer [2] is presented. The die area and power dissipation are reduced by using time-multiplexed sampling and dut...
