When it comes to tracking an athlete’s performance, a single wearable sensor does not always provide a lot of information, but multiple hard wired sensors limit movement. That’s what a new sensor service does – it’s powered by a smartphone. The battery free garment, developed by the National University of Singapore team, contains custom sensors that are connected together by wires sewn into the fabric. < / P > < p > when the smart phone is placed on or near a conductive coil of the line, its NFC (near field communication) signal will temporarily activate the sensors, allowing them to send the stored readings back to the phone. The data is then displayed on the device’s screen. < / P > < p > in the current prototype, the device can support up to six sensors per smartphone. These sensors provide data on factors such as running gait, body temperature and spinal posture. The latter is particularly important because, according to the University, “spinal posture is an integral part of developing a solid athletic posture and is often overlooked because of the difficulty of collecting real-time data.” < / P > < p > once further developed, the technology can also be used to evaluate medical clothing for spinal diseases or clothing for continuous monitoring of vital signs of patients. If used in sportswear, it can not only assess performance, but also warn if the wearer is in danger of overheating. < / P > < p > “our smart services can be used with most modern smartphones, both as a source of power and as a display for viewing sensor data.” Chief scientist he Junjie, associate professor said. “The creation of a smart service that can be powered by wireless technology with built-in smartphones is a major breakthrough.” Global Tech
