is an AFM-based technique for materials and device characterization. The reflected microwave signal from the tip-sample interface holds information of the electrodynamic properties of the sample surface underneath the tip apex. Detecting and processing of the reflectance in real time allows sMIM to directly access the permittivity and conductivity of materials. When an AFM-type sMIM probe is sc...

This paper presents a power-efficient complementary metal-oxide-semiconductor (CMOS) neural signal-recording read-out circuit for multichannel neuromodulation implants. The system includes amplifier and successive approximation register analog-to-digital converter (SAR-ADC) recording digitizing signal data to transmit remote receiver. synthetic is generated using LabVIEW myDAQ device processed ...

Impedance measurements are crucial in a variety of applications, from the characterization lithium batteries, microbial fuel cells, and biosensors to study polymers material degradation, where strict requirements have be met terms frequency bandwidth current level. Here, we present cost-effective compact solution for ultra-low-frequency impedance measurements, operating wide range, 1 mHz 250 kH...

Global on-chip data communication is becoming a concern as the gap between transistor speed and interconnect bandwidth increases with CMOS process scaling. In this paper a low-swing transceiver for 10mm long 0.54μm wide on-chip interconnect is presented, which achieves a similar data rate as previous designs (a few Gb/s), but at much lower power than recently published work. Both low static pow...

Capacitive deionization (CDI) is a promising desalination technology based on electrosorption the surfaces of microporous electrodes. However, low total dissolved solids (TDS) in water restricts its efficacy. In this work, we develop theory capacitive spacers (CS) CDI. The investigations reveal mechanism that call ohmic charging; is, resistive losses spacer region drive adsorption CS. As conseq...

In this paper we present an electronic circuit for position or capacitance estimation of MEMS electrostatic actuators based on a switched capacitor technique. The circuit uses a capacitive divider configuration composed by a fixed capacitor and the variable capacitance of the electrostatic actuator for generating a signal that is a function of the input voltage and capacitive ratio. The propose...

This study proposes the use of flexible capacitive electrodes for reducing motion artifacts in a wearable electrocardiogram (ECG) device. The capacitive electrodes have conductive foam on their surface, a shield, an optimal input bias resistor, and guarding feedback. The electrodes are integrated in a chest belt, and the acquired signals are transmitted wirelessly for ambulatory heart rate moni...

The resistive wall impedance in the SPS causes transverse coupled bunch instabilities, that have to be cured by active feedback. The status of the upgrade program for the feedback system (damper) will be reviewed. Results of machine development sessions of 1999 will be presented with emphasis on the performance with LHC type beam. Plans for the year 2000 run are outlined.

Downsizing electronic and electric equipment requires the optimization of field distributions in order to avoid localized dielectric breakdown (also called partial discharges). This paper presents a novel composite material aimed at grading electrical local surface stress. functional has conductivity which increases by several orders with applied giving ability distribute itself.
