The wearable market has gradually heated up since the second half of 2013, and many big-name companies have launched their first generation products, such as Baidu, Huawei, TCL and the recent Xiaomi. These companies' first-generation products have relatively simple functions, mainly counting steps, calorie calculations, sleep detection, vibration alarm clocks, etc., connected to mobile phones through Bluetooth 4.0 technology, basically using the semiconductor industry's low power consumption and relatively small package. General-purpose chips, these products have been mass-produced before the wearable market heats up. As the market heats up, the functions of the new generation of smart bracelets and smart watches will further increase, and higher requirements will be placed on power consumption and volume. As a professional partner of STMicroelectronics in the domestic wearable market. Wuhan Liyuan is committed to promoting ST's new generation of chips optimized for packaging, performance and power consumption in the wearable market, including 32-bit CortexTM-M0+ and CortexTM-M4 core CPUs, static 150mA LDO STLQ015 with current as low as 1.4uA. Low-power Bluetooth 4.0 chip BlueNRG chip as small as 2.6*2.6mm WCSP34 package and acceleration gyroscope including 3-axis (3A), 6-axis (3A+3G), 9-axis (3A+3G+3M), The motion sensor of the magnetometer and the environmental parameter sensor including temperature and humidity, air pressure and ultraviolet light. Most of the above sensors are powered by 1.7-3.5V, and the 2*2mm small package greatly reduces the size, which makes it possible to realize the realization of a new generation of more compact wearable devices. In addition, ST has almost all the chips that need to be used in wearable products, which makes it more advantageous in terms of technical support, supply and price.

Due to the rapid replacement of the wearable market, the time from definition to completion of design, production, testing, and time-to-market is generally 6 months, and there are many technical categories involved, unlike general electrical signal collection, wearable products. Mainly to collect physiological parameters, such as ECG, blood sugar, blood oxygen, heart rate, etc., while the motion detection part involves the calculation of exercise posture, exercise volume, and Bluetooth communication technology. These technologies are for traditional electronic products companies. The technical accumulation is very weak. In response to this situation, Liyuan Information follows the customer's application and timely launches a series of reference designs and complete solutions, focusing on solving technical difficulties and lowering technical thresholds, enabling enterprises to concentrate on marketing and shortening products. Time to market. Two complete solutions for the Bluetooth 4.0 module, two DIMO boards and smart wristbands, and the GPS/GLONASS dual-mode navigation module have been introduced (refer to the picture below). At present, a number of companies have signed an NDA agreement with us, using the technology of our reference design, and some of the manufacturers' products have been available to the market and achieved good results.
The wearable market has only just started in 2014, and the subsequent development momentum is infinite. Now it has shown a diversified trend. The chip that adds the NFC card to the smart bracelet can be used in the traditional payment, access control and other industries. Future Power Information will invest more in key algorithms, development platforms including software and hardware, and innovative industry applications, and continue to maintain its leading position in the wearable industry.
