On December 5th, IDC's latest report showed that in the third quarter of 2016, the global wearable market continued to be weak, with an overall sales volume of 23 million, maintaining a slight growth of 3.1%. In the top five of the overall market, sales of smartwatch Apple Watch fell 71% year-on-year. The other four are bracelet manufacturers, showing a high growth.
Despite this, it is reported that wearable devices will be everywhere in the CES 2017 show. Sports tracking systems, smart watches, heart rate monitors and helmets will all be on display at this show. There will be new technologies or products that will drive the development of the health technology industry.
We know that the birth of a new product requires several stages: first, prototype design, verification of basic functions, subsequent design and testing, and finally optimized design and mass production. In order to further accelerate the realization of product developers from ideas to products, from functional prototypes to design, in recent years, major semiconductor manufacturers are also actively launching wearable development platforms. Let's take a look at the mainstream wearable device chip development platforms.
1, Dialog's lowest power 12-degree-of-freedom Bluetooth intelligent sensor development platform
Dialog Semiconductor's world's lowest power and smallest 12-degree-of-freedom (DoF) wireless smart sensor development platform suite for IoT applications, Dialog's DA14583 SmartBondTM Bluetooth Smart SoC and Bosch Sensortec's gyroscopes, accelerometers, The magnetometer and environmental sensor are integrated on a 16mm x 15mm micro printed circuit board. The board is in the form of a dongle with a plastic case on the outside. Typical current consumption is only 1.3 mA when transmitting sensor data, below 110 μA in broadcast mode and below 11 μA in power saving mode.
The new development platform accelerates the development of environmental and motion sensor modules for wearable devices, virtual reality, 3D indoor maps and navigation, remote controls and many other IoT sensor-based applications. It transmits raw sensor data and outputs the absolute actual orientation of the device in quaternion form.
The companion Software Development Kit (SKD) includes Dialog's SmartFusionTM intelligent sensor library for data acquisition, auto-calibration and sensor data fusion, and runs on the DA14583 Cortex M0 processor.
A 12-degree-of-freedom (DoF) sensor combines position and motion sensing information with magnetic fields and ambient data to provide optimal tracking of human activity. Dialog's sensor development kit can also be used for the development of 9-axis system applications. The Bosch sensors in the development kit include the BMI160 6-axis inertial measurement unit, the BMM1503 axial geomagnetic sensor, and the BME280 integrated environmental unit for pressure, temperature and humidity.
2, Freescale wearable reference design platform WaRP
The wearable product is one of the ultimate edge node sensors for the Internet of Things. Freescale's wearable reference platform WaRP uses a scalable modular hybrid structure that greatly simplifies the design and development time of wearable products. The solution enables designers and originals. Equipment manufacturers can turn concepts into prototypes as quickly as possible as the market changes.
As an ARM architecture wearable system platform, Freescale and KyneTIcs, RevoluTIonRoboTIcs, Circuitco and other more than fifteen vendors, open source, scalable reference platform - WaRP (Wearable Reference Platform). The platform is available in a variety of models or product categories, and its highly flexible system-level design suite supports embedded wireless charging, integrating processors and sensors into a hybrid architecture for scalability and flexibility.
The WaRP hybrid architecture consists of a motherboard and an example daughter card with the i.MX6SoloLiteARMCortex-A9 processor as the platform core. The standby microprocessor KineTIsKL16MCU on the example daughter card is used as a sensor hub (SensorHub) and can also be used for different Use the mode to add more daughter cards, and also equipped with a wireless charging MCU.
Sensor technology is an important part of wearable devices. WaRP includes the Freescale Xtrinsic NMA9553 pedometer and the FXOS8700 electronic compass, which runs the Android 4.3 operating system. The hybrid architecture allows processors to communicate with each other and support graphical display. In deep sleep mode, the KinetisKL16 can still collect sensor data, which reduces overall platform power consumption and extends standby time.
Applications supported by WaRP include motion tracking, smart watches, electrocardiogram (ECG) monitoring, smart glasses, augmented reality head-mounted displays, wearable medical products, and more. SujataNeidig, a Freescale Microcontroller Business Unit, believes that the open-source WaRP platform can reduce the threshold for wearable device development and speed time-to-market. Neidig pointed out that in addition to providing key components such as microprocessors (MPUs), microcontrollers (MCUs), and micro-electromechanical systems (MEMS) sensors to developers, WaRP accelerates the overall wearable market and lowers the development threshold. Many small and medium-sized start-up companies have successfully developed wearable devices.
Because WaRP appeals to an open platform, in order to comply with its open source features, the device currently supports open operating systems such as Android and Linux; while AndroidWear is still a closed ecosystem, whether it is a software development kit (SDK), The application is not yet fully open and only locks the smartwatch app, so WaRP is currently not supported, but once AndroidWear is fully open source, WaRP will definitely include it in its supported systems.
