The quantification and detection of biochemical species are of utmost importance for biomedical applications. Silicon nanowire field-effect transistors (SiNW-FETs) have recently attracted tremend ... Read More

Osteoarthritis (OA) is one of the most common causes of disability in elderly individuals. Although X-rays, MRIs, and arthroscopy are widely used to examine OA, they do not provide dynamic infor ... Read More

In this paper, we present a robot outdoor patrol that applies a differential global positioning system (DGPS), an encoder, a web camera, and a laser sensor with an improved A* algorithm to achiev ... Read More

A gait monitoring system based on liquid pressure detection was designed. In this work, based on the study of the plantar pressure distribution, a special cylindrical liquid cavity was located u ... Read More

In this paper, we present a distributed interference-aware medium access control (DI-MAC) for IEEE 802.15.7 visible light communications (VLCs), which improves the spatial efficiency of VLC devic ... Read More

This paper presents a first-order delta-sigma (ΔΣ) capacitance-to-digital converter (CDC) with low noise characteristics and a reconfigurable resolution of 12 to 16 bits. The proposed ΔΣ CDC ... Read More

In this study, a system supporting disaster surveillance and response decisions is investigated. In a multisensor surveillance system, distributed sensor nodes such as cameras can sense, monitor ... Read More

The global positioning system (GPS) sensor has had a considerable impact on almost all positioning, navigation, timing, and monitoring applications. It provides spread spectrum satellite signals ... Read More

Concern about energy-efficient medium access control (MAC) protocols for wearable devices is increasing owing to support for healthcare services using wireless body sensor networks (WBSNs). The ... Read More

This paper presents a message queue telemetry transport (MQTT) broker with priority support for emergency events in the Internet of Things (IoT), which is abbreviated p-MQTT. To support the time ... Read More

The Internet of Things (IoT) is a very popular research topic, which provides consumers more autonomy with commodity. It leads the commodity towards small-volume/multiple-type production of tren ... Read More

This paper presents a regional density-aware data collection (RDDC) using unmanned aerial vehicles (UAVs) in large-scale wireless sensor networks (WSNs). The RDDC is designed to support fast dat ... Read More

In this study, a pre-impact fall detection algorithm using a custom-made inertial sensor was optimized, and a spring-trigger airbag system was developed for preventing injuries from falls. Four ... Read More

With over four decades spent collecting spaceborne moderate-resolution imagery, Landsat represents the longest remote sensing mission in the world, and has had various applications. Land cover m ... Read More

In this paper, an energy-efficient 11.49-bit successive approximation register (SAR) capacitance-to-digital converter (CDC) for capacitive sensors with a figure of merit (FoM) of 31.6 pJ/conversi ... Read More

Construction activities, involving cutting, drilling, and grinding of materials, often produce toxic respirable dust that can cause fatal diseases and illnesses. To protect workers from breathi ... Read More

There have been many studies on strain-resistance or piezoresistance e-textile sensors. However, the important and critical factor, i.e., the elongation capability of the sensor against the actu ... Read More

The three-phase, four-cable type of power distribution lines branch into multiple circuits from local pole- or pad-mounted transformers, which makes the topology of lines complicated. A challeng ... Read More

Increases in skin temperature and accumulation of moisture during prolonged sitting are risk factors for pressure ulcers. Therefore, a method of assessing temperature and moisture between the bo ... Read More
