Abstract: This work represents active DNA concentration on piezoresistive microcantilever using biased AC electroosmosis. Two different sizes of DNA molecules, -phage DNA (48.5 kbp) and single-strand DNA of 20 nucleotides are concentrated on separate piezoresistive microcantilever sen- sor for detection. Before concentration, mixing of DNA molecules is performed using the same device for efficient concentration. During concentration of DNA molecules, biased and unbiased AC elec- troosmosis are needed to concentrate single-strand DNA and -phage DNA, respectively. Moreover, dielectrophoresis is induced by biased AC electroosmosis that can generate attractive force to trans- port negatively charged single-strand DNA. This paper represents a device configuration to integrate biased and unbiased AC electroosmosis and dielectrophoresis with piezoresistive microcantilever sen- sors for the detection of -phage DNA and single-strand DNA.

Abstract: This work presents a microfabricated fringe-field capacitive pH sensor using interdigitated electrodes and an integrated modulation-based readout circuit. The changes in capacitance of the sensor result from the permittivity changes due to pH variations and are converted to frequency shifts using a crossed-coupled voltage controlled oscillator readout circuit. The shift in resonant frequency of the readout circuit is 30.96 MHz for a change in pH of 1.0–5.0. The sensor can be used for the measurement of low pH levels, such as gastric acid, and can be integrated with electronic pills. The measurement results show high repeatability, low noise, and a stable output.

Abstract: Ultralight graphene elastomer-based flexible sensors are developed to detect subtle vibrations within a broad frequency range. The same device can be employed as an accelerometer, tested within the experimental bandwidth of 20-300 Hz as well as a microphone, monitoring sound pressures from 300 to 20 000 Hz. The sensing element does not contain any metal parts, making them undetectable by external sources and can provide an acceleration sensitivity of 2.6 mV/g, which is higher than or comparable to those of rigid Si-based piezoresistive microelectromechanical systems (MEMS).

Abstract: This work reports on the behavior of piezoresistive microcantilever sensors under optimizing conditions of ac electroosmotic enhancement. Piezoresistive microcantilevers are used as sensor elements for detection of concentrated bio-particles. Without preconcentrating the s les, using ac electroosmosis, these bio-particles have been manipulated onto the piezoresistive microcantilever. A piezoresistive microcantilever senses the dimensional changes upon particle exposure as a resistance change. This paper represents the integration of ac electroosmosis with a piezoresistive micro-cantilever sensor for the detection of bio-particles. A working prototype is presented here, and the experiments are conducted on Herpes Simplex type-1 virus (HSV-1) and Escherichia Coli (E. coli) bacteria.
