Abstract Terahertz (THz) wave plays important roles in the research of material properties, non-invasive human security check and next generation wireless communication. The progress scientific technological applications THz is strongly dependent on improvement detectors. Here a novel detection scheme proposed which radiation detected by an audible microphone based photo-thermo-acoustic (PTA) e...

Solid-state photon detectors based on semiconductors other than silicon are not yet considered mature technology but their current development opens new possibilities, also for space observations. Such devices are especially attractive for ultraviolet radiation detection, as semiconductor materials with band gaps larger than that of silicon can be produced and used as “visible-blind” or “solar-...

Free-space optical (FSO) communication is a cost effective and high data rate access technique, which has been proving itself a best alternative to radio frequency technology. FSO link provides high bandwidth solution to the last mile access bottleneck. However, for terrestrial communication systems, the performance of these links is severely degraded from atmospheric loss mainly due to fog, ra...

BACKGROUND Early and non-invasive determination of blood glucose level is of great importance. We aimed to present a new technique to accurately infer the blood glucose concentration in peripheral blood flow using non-invasive optical monitoring system. METHODS The data for the research were obtained from 900 individuals. Of them, 750 people had diabetes mellitus (DM). The system was designed...

The problem of drifting charge-induced currents is considered in order to predict the pulsed operational characteristics in photo-and particle-detectors with a junction controlled active area. The direct analysis of the field changes induced by drifting charge in the abrupt junction devices with a plane-parallel geometry of finite area electrodes is presented. The problem is solved using the on...

This paper presents the design, fabrication and characterization of CMOS (complementary metal oxide semiconductor) micromachined grippers with on-chip photo detectors placed beneath the gripping sites. The fabrication features a combination of metal wet etch and sacrificial polysilicon etch for structural release. The fabricated microstructure contains metal and dielectric layers, plus a polysi...
