Localization and mobility monitoring are fundamental functions for constructing a smart living space. This paper presents a smart living platform based on motion sensing carpets. It is developed in the form of 50×50cm ‘puzzle floor mat’ units, which allows the users to assemble by themselves according to their desired shape and area. From the pressure data collected by motion sensing carpets, functions...
This paper presents the design, implementation and experimental results of an energy harvesting system to extract energy from power transmission lines. The energy is extracted from a high permeability core clamped on a high alternative current cable. A coil wound on the magnetic core can harvest energy effectively from the power line when the core is operating at the non-saturation region. Little...
In this letter, a first study on phosphate detection based on AlInN/GaN high electron mobility transistors (HEMTs) is presented. The ungated regions of GaN HEMT-based sensors were functionalized with the phosphate ion-imprinted polymer and their sensing behaviors were analyzed by detecting different concentrations of phosphate solutions. The results show that the AlInN/GaN sensor exhibits an ultrasensitive...
A refractive index fiber sensor was constructed by deposition of carbon nanotubes onto a joint segment of single-mode and multi-mode fibers. A maximum sensitivity of 157.9 dB/RIU for the RI range of 1.33–1.45 was achieved.
Reflectance-based photonic crystal (PC) sensors with ALD TiO2 pillars for sensing materials with different refractive index (RI) are presented here. The relatively high RI, transparency in visible and IR region and chemical stability make TiO2 a promising material for PC sensors for applications in food or biomedical industry. An IC-compatible fabrication technique called Atomic layer deposition ARrays...
Wearable devices are a novel method for sensing physiological parameters of subjects. Even though some of them are equipped with multiple sensors, usually each parameter is analyzed separately. It often leads to false alarm generation and thus limited acceptability of these systems. We propose not only to combine multi-sensor data available on the wearable device, but also to interface the wearable...
