On July 9, 2015, Dalian United Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its company will launch a low-power Bluetooth smart wearable solution based on Atmel, TI and Toshiba.
The smart wearable solution is to intelligently design and develop daily wear to help people better perceive the information of the outside and themselves. From smart watches to fitness trackers, the market for wearable devices has shown significant growth. According to internationally renowned electronic product research organizations, the number of tracking devices such as smart watches and fitness wristbands will reach approximately 70 million in 2015. 38% more than in 2014 and will reach an astonishing 514 million pieces by 2020.
The market share of wearable devices using Bluetooth as a wireless communication method is rapidly increasing, so it is expected that Bluetooth 4.0 BLE (Bluetooth Low Energy) technology will soon become the default connection method for wearable technologies or devices.
