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...
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...
Implantable devices have important applications in biomedical sensor networks used for biomedical monitoring, diagnosis and treatment, etc. In this paper, an implant intra-body communication (IBC) method based on capacitive coupling has been proposed, and the modeling and characterization of this kind of IBC has been investigated. Firstly, the transfer function of the implant IBC based on capac...
We are working toward actualizing a real-time 3D modeling system. It uses a sensor network that distributes many 1 mm-class sensor nodes in plastic clay. The distributed sensors sense distances between them, and the sensor network collects the distance information for recognizing object shape by calculating relative positions of nodes based on the collected node-to-node distances. This paper pr...
Advanced capabilities in electrical recording are essential for the treatment of heart-rhythm diseases. The most advanced technologies use flexible integrated electronics; however, the penetration of biological fluids into the underlying electronics and any ensuing electrochemical reactions pose significant safety risks. Here, we show that an ultrathin, leakage-free, biocompatible dielectric la...
As technology scales into the deep submicron regime, capacitive coupling between signal lines becomes a dominant problem. Capacitive coupling is more acute for domino logic circuits since an irreversible, unwanted gate output transition can result. We present a timed test generation methodology for CMOS domino circuits that assigns the circuit inputs so that capacitively-coupled aggressors of a...
We study the thermal interaction between two nearby thin metallic wires, at finite temperature. It is shown that the Johnson currents in the wires give rise, via inductive coupling, to a repulsive force between them. This thermal interaction exhibits all the puzzling features found recently in the thermal Casimir effect for lossy metallic plates, suggesting that the physical origin of the diffi...
We demonstrate milling of partial antenna gaps and narrow conducting bridges with nanometer precision using a helium ion beam microscope. Single particle spectroscopy shows large shifts in the plasmonic mode spectrum of the milled antennas, associated with the transition from capacitive to conductive gap loading. A conducting bridge of nanometer height is found sufficient to shift the antenna f...
Based on a capacitive angle and angular rate sensor, a sensor measuring the relative angle between two rotating shafts has been developed. Two rotatable electrodes are placed between two sensor plates. The relative angle between the two rotors and the absolute position of the rotor blades are calculated from measurements of the capacitive coupling between different transmitting stator segments ...
You work in a characterization laboratory af a MEMS company, and you have to design an electronic board in order to test a given capacitive accelerometer. The application of the sensor is vibration monitoring on a mechanical engine in a specific frequency range (from 40 Hz to 400 Hz). The MEMS device has a mass of 8nK g , a mechanical stiffness of 5N /m and a quality factor Q = 2. The capacitiv...
