Physiological rehabilitation is applied in medical practice to restore a person's functional ability after musculoskeletal injuries. Movements the joints are main indicator of activity organs support and movement. The paper considers resistive goniometric sensor form ball joint. Based on such sensor, system developed. It includes also data collection device (autonomous recorder) portable modem....

A study on the application of V(2)O(5)/WO(3)/TiO(2) (VWT) as the sensitive material for resistive-type SO(2) sensor was conducted, based on the fact that VWT is a well-known catalyst material for good selective catalytic nitrogen oxide reduction with a proven excellent durability in exhaust gases. The sensors fabricated in this study are planar ones with interdigitated electrodes of Au or Pt. T...

We present an integrated microelectronic device for amplification and label-free detection of nucleic acids. Amplification by polymerase chain reaction (PCR) is achieved with on-chip metal resistive heaters, temperature sensors, and microfluidic valves. We demonstrate a rapid thermocycling with rates of up to 50 degrees C s(-1) and a PCR product yield equivalent to that of a bench-top system. A...

A non-dispersive infrared (NDIR) methane gas sensor prototype has achieved a minimum detection limit of 1 parts per million by volume (ppm). The central idea of the design of the sensor is to decrease the detection limit by increasing the signal to noise ratio (SNR) of the system. In order to decrease the noise level, a single frequency filter algorithm based on fast Fourier transform (FFT) is ...

The current paper reports on a sonochemical synthesis method for manufacturing nanostructured (typical grain size of 50 nm) SrTi0.6Fe0.4O2.8 (Sono-STFO40) powder. This powder is characterized using X ray-diffraction (XRD), Mössbauer spectroscopy and Scanning Electron Microscopy (SEM), and results are compared with commercially available SrTi0.4Fe0.6O2.8 (STFO60) powder. In order to manufacture ...

This paper presents Cantion’s cantilever-based bio/chemical sensor. The cantilevers have integrated readout and can be used both in liquids and gases. The sensing principle is based on a cantilever bending due to a change in surface stress. Such surface-stress change is obtained during molecular interaction which has made it possible to measure DNA hybridization, antigen-antibody interactions e...

In this paper we present a novel split-current magnetic sensor (bulk Hall plate operated in the current mode) with onchip circuitry, fabricated in an industrial 2 pm CMOS process. The sensor consists of a low-doped resistive path with one input and three output terminals. The on-chip circuit controls the biasing of the sensor, calculates the difference between the currents flowing through the o...

A gray TiO₂/SrTiO₃ composite nanocrystalline sensor with narrow band-gap was successfully prepared through a facile wet chemical method. The precursor was calcined in N₂ flow under atmospheric pressure and thereafter, a humidity sensor based on the composite was fabricated. The sensor showed high resistive sensitivity and varied by more than four orders of magnitude with an increase in relative...

This paper presents a Universal Micro-Sensor Interface (UMSI) circuit designed for low-power microsystems that support multiple sensors and actuators. The interface chip contains all necessary reference, readout, control, and communication circuitry to interface a range of capacitive, resistive, voltage, or digital output devices to system control hardware. For online configuration of many para...

This paper describes a high-temperature pressure-transducer interface for resistive Wheatstone bridges. The long-term drift of the smart sensor, i.e., the (pressure) sensor plus its interface electronics, will be determined by the drift of the sensor element only. A three-signal auto-calibration sequence of the interface electronics keeps the transducer interface virtually free of long-term dri...
