Towards an Implantable, Low Flow Micropump That Uses No Power in the Blocked-Flow State
Low flow rate micropumps play an increasingly important role in drug therapy research. Infusions to small biological structures and lab-on-a-chip applications require ultra-low flow rates and will benefit from the ability to expend no power in the blocked-flow state. Here we present a planar micropump based on gallium phase-change actuation that leverages expansion during solidification to occl...
متن کاملContinuous-Time ∆Σ Modulators for Ultra-Low-Power Radios
The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuoustime ∆Σ modulators...
متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
متن کاملTheoretical Evaluation of Electroactive Polymer Based Micropump Diaphragm for Air Flow Control
An electroactive polymer (EAP), high energy electron irradiated poly(vinylidene fluoride-trifluoroethylene) [P(VDFTrFE)] copolymer, based actuation micropump diaphragm (PAMPD) have been developed for air flow control. The displacement strokes and profiles as a function of amplifier and frequency of electric field have been characterized. The volume stroke rates (volume rate) as function of elec...
متن کاملanovelmethod for ultra trace measurement of bentazon based on nanocomposite electrode and continuous coulometric fftcyclicvoltammetry
in this work, a novel electrochemical technique is presented for determination of bentazonusing a nanocomposite based sensor and continuous coulometric fast fourier transformation cyclicvoltammetry (ccfftcv). in this method, the sensor response is in coulomb and is calculated based onintegrating charge changes under the current voltammogram in selected potential range. the new sensor wasconstru...
