We present a small, compact and portable device for point-of-care instantaneous early detection of anemia. The method used is based on direct hematocrit measurement from whole blood samples by means of impedance analysis. This device consists of a custom electronic instrumentation and a plug-and-play disposable sensor. The designed electronics rely on(More)
The first part of this paper reviews the current development and key issues on implantable multi-sensor devices for in vivo theranostics. Afterwards, the authors propose an innovative biomedical multisensory system for in vivo biomarker monitoring that could be suitable for customized theranostics applications. At this point, findings suggest that(More)
The present paper reports a bacteria autonomous controlled concentrator prototype with a user-friendly interface for bench-top applications. It is based on a microfluidic lab-on-a-chip and its associated custom instrumentation, which consists of a dielectrophoretic actuator, to preconcentrate the sample, and an impedance analyzer, to measure concentrated(More)
Bacteria concentration and detection is time-consuming in regular microbiology procedures aimed to facilitate the detection and analysis of these cells at very low concentrations. Traditional methods are effective but often require several days to complete. This scenario results in low bioanalytical and diagnostic methodologies with associated increased(More)
We describe a novel continuous-flow cell concentrator microdevice based on dielectrophoresis, and its associated custom-made control unit. The performances of a classical interdigitated metal electrode-based dielectrophoresis microfluidic device and this enhanced version, that includes insulator-based pole structures, were compared using the same setup.(More)
A novel piezoelectric harvester-based self-powered adaptive solution with wireless data transmission capability for structural health monitoring is presented. This work demonstrates the accomplishment of maximum power transferred condition for a wide range load conditions and for different amplitudes and frequencies oscillation of the piezoelectric(More)
In this paper, a compact system for point-of-use EIS (Electrochemical Impedance Spectroscopy) experiences is described. This is based on a custom electronic instrumentation, post processing software and low-cost disposable three-electrodes sensor. The designed electronic is based on a signal generator, a potentiostat and a digital lock-in amplifier(More)
