Starfish and octopuses control their infinite degreeof-freedom arms with panache—capabilities typical of nature where the distribution of reflex-like intelligence throughout soft muscular networks greatly outperforms anything hard, heavy, and man-made. Dielectric elastomer actuators show great promise for soft artificial muscle networks. One way to make them smart is with piezo-resistive Dielec...

D id you ever notice how complicated your life is becoming? Back in the good o ld days, resistors with a 20% tolerance rating were basic in all electronic circuitry. Through the years w e have "progressed" through the 20% to 10% to 5% to 1 % tolerance resistors. Granted there are many circuits where the 20% resistors are still used quite extensively, but as we strive for higher precision, lower...

Zinc oxide is one of the most popular materials for acoustoelectronic sensors and vibro-piezo-transducers used in nano-piezo-generators. In present paper, thick piezoelectric ZnO films are fabricated on both sides various substrates using magnetron sputtering technique.

This paper analyzes the effect of the fuzzy logic-controlled braking resistor (BR) on minimizing shaft torsional oscillations of the generators in a multi-machine power system. The influence of communication delay associated with the fuzzy controller input calculation on minimizing shaft torque oscillations is investigated. Global Positioning System (GPS) is proposed for the practical implement...

Methodsfor predictingthe performanceof laser-trimmed film resistors taking into account the properties of the heat-affected zone (HAZ) are discussed. A figure of merit based npon a sensitivity fnnction called HAZ sensitivity, SHA z , is introduced which is useful for determining aging and temperature effects of an arbitrary film-resistor geometry with an arbitrary trim strategy. ~H4 z is also s...

A low voltage switched-capacitor circuit that generates an almost constant reference current across process, voltage and temperature (PVT) is proposed. The reference voltage is generated by a low voltage band-gap circuit. The output reference current is obtained by applying the generated reference voltage to a low voltage V – I converter. The resistor in the proposed V – I converter is further ...

This paper proposes a new DAC BIST (digital-to-analog converter built-in self-test) structure using a resistor loop known as a DDEM ADC (deterministic dynamic element matching analog-to-digital converter). Methods for both switch reduction and switch effect reduction are proposed for solving problems related to area overhead and accuracy of the conventional DAC BIST. The proposed BIST modifies ...

We propose a CMOS circuit that can be used as an equivalent to resistors. This circuit uses a simple differential pair with diodeconnected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region of MOSFETs. Its resistance can be controlled in a range of 1–1000 MΩ by adjusting a tail current for the differential pair. The results of device fabrication with a 0.3...

Printing functional materials represents a considerable impact on the access to manufacturing technology. In this paper we present a methodology and validation of print-and-self-fold miniature electric devices. Polyvinyl chloride laminated sheets based on metalized polyester film show reliable self-folding processes under a heat application, and it configures 3D electric devices. We exemplify t...
