Introduction: This study describes a thin and low-cost capacitive pressure sensor in touch mode (TM) for monitoring fluid pressure from 0 to 40kPa in fluidic chambers with Luer fittings for medical applications. TM provides good linearity, large measuring range and large overload ... Per saperne di più
We report on the modeling of flexible piezoelectric capacitive sensor based on GaN wires grown by Metal Organic Vapor Phase Epitaxy. Single crystal cone-shaped wires with hexagonal cross section are embedded within dielectric layers (parylene) in between two metal electrodes to achieve a ... Per saperne di più
In power electronics applications, microelectronic chips face swift temperature changes during operation, characterized by heat pulses of sub-millisecond duration with temperatures rising by hundreds of Kelvin. Over time, these conditions may lead to degradation in the metallization ... Per saperne di più
Sleep apnea is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. There is a need to diagnose sleep apnea since it leads to fluctuations in the oxygen level that in turn affect the heart rate and blood pressure. In ... Per saperne di più
Surface acoustic wave (SAW) devices are widely used for their sensing capabilities and gas sensing is only one of many uses. There is an ever increasing need to make them as effective as possible by adding nanomaterials to the device. In this study a two-port delay-line structure with ... Per saperne di più
