Heart rate monitoring using wrist-type photoplethysmographic (PPG) signals during subjects’ intensive exercise is a difficult problem, since the signals are contaminated by extremely strong motion artifacts caused by subjects’ hand movements. So far few works have studied this problem. In this work, a general framework, termed TROIKA, is proposed, which consists of signal decomposiTion for deno...

Watches are wearable devices that support human activities as timepieces. There two types of watches based on their source driving energy: the quartz type, which uses a battery, and automatic mechanical mechanism to convert kinetic energy obtained when clock is used drive hands. Automatic type have time limit 48 hours or days until turns off stop. Therefore, watch winder needed make movements k...

In the era of Internet Things, digital displays play a critical role in human–machine interfaces. particular, applied to contemporary devices such as flexible smart watches and foldable/rollable electronics underline need for pertinent materials device technologies fulfill their designed functions. However, despite technical advancements electronic components stretchable/flexible electrodes bac...

The Internet of Things (IoT) is used to describe a network physical objects which are connected each other with the help embedded sensors, transceivers and software code communicate share data other. Things, first took shape back in 1980s through an ARPA-NET Coca-Cola Vending machine Carnegie Mellon University has come long way since then. In today’s world growing proportion new home appliances...

A new survey of Mars Orbiter Camera (MOC) narrow-angle images of gullies in the 30◦–45◦ S latitude band includes their distribution, morphology, local topographic setting, orientation, elevation, and slopes. These new data show that gully formation is favored over a specific range of conditions: elevation (−5000 to +3000 m), slope (>10◦), and orientation (83.8% on pole-facing slopes). These dat...

It is important to develop Martian soil simulants that can be used in Mars exploration programs and Mars research. A new Martian soil simulant, called Jining Martian Soil Simulant (JMSS-1), was developed at the Lunar and Planetary Science Research Center at the Institute of Geochemistry, Chinese Academy of Sciences. The raw materials of JMSS-1 are Jining basalt and Fe oxides (magnetite and hema...

Abstract Sleep-wake disturbances are among the most common and severe symptoms in primary brain tumor (PBT) patients. Currently, no studies have quantified their physiological sleep measurements or compared these assessments to established patient reported outcome measures (PROs). Smart wearable devices, such as Fitbits, continuously monitor behaviors at home provide detailed of sleep, activity...
