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...

Oxygen-containing functional groups were introduced onto the surface of the micro- and meso-porous silicon carbide sphere (MMPSiC) in order to investigate the relationship between the electric double layer properties and pseudo-capacitive properties; the degree of oxidation of MMPSiC was also optimized. Although the oxygenated surface functionalities can lead to a decrease in the surface area o...

We present a novel approach of active object categorization based on an iterative Bayesian method using capacitive sensing during object manipulation. The approach uses a novel type of capacitive sensor, which can measure internal properties of materials that are inaccessible to vision or tactile sensing. The electrodes of this capacitive sensor are sufficiently flexible and thin to be attached...
