There is an increasing demand for flexible and wearable strain sensors for the potential applications in wearable monitor, including human activities, human-machine interfaces and master devices for teleoperated robotic system, etc. Herein, we propose a highly stretchable strain sensor developed by structured single-walled carbon nanotube /carbon black (SWCNTs/CB) networks for wearable monitor. The...
PM2.5 (particulate matter in the atmosphere with a diameter no more than 2.5 microns) in the air can cause great damage to human beings. It's a great challenge to offer a fine-grained and accurate PM2.5 monitoring service in urban areas as the required facilities are very expensive and huge. Since the PM2.5 has a significant scattering effect on visible light, the large-scale user-contributed image...
Air pollution has become one of the most pressing environmental issues in many countries, including China. Finegrained PM2:5 particulate data can prevent people from long time exposure and advance scientific research. However, existing monitoring systems with PM2:5 stationary sensors are expensive, which can only provide pollution data at sparse locations. In this paper we demonstrate for the first...
Aiming for monitoring the existed mobile services, we are here to propose an automatic dial testing system for mobile services. Firstly we sketch out the dial testing method, and then propose the whole framework of the mobile dial testing system, comparing with the traditional way. After that, we elaborate the whole process of a dial testing in every detail. Finally, we comprehensively test the voice...
