In 2015, the State Council's guidance on actively promoting the "Internet +" initiative pointed out that giving full play to the efficient and convenient advantages of the Internet, improving resource utilization efficiency, and reducing service consumption costs, and further integration of intelligent hardware and the Internet of Things also fall into this category. With the Internet of Things and big data, smart hardware can be better integrated into life and form a whole ecosystem. Therefore, supporting smart health product innovation and application, hardware and software are fully integrated, and promoting a new way to quantify healthy living has become a hot topic. Encourage health service organizations to use cloud computing, big data and other technologies to build public information platforms, and provide personalized health management services for long-term tracking, forecasting and early warning. Encourage service organizations to apply mobile Internet-based portable medical examinations and other equipment. Here I have to mention that the current smart devices are involved in medical health. In the first half of 2015, leading representatives from different industries entered the field of intelligent hardware, and the application of medical health, home entertainment, and fitness as a symbol was widely promoted. This made us have to think deeply about how to ensure that smart hardware plays a role in medical health. Its due role.
Health Intelligence Hardware Development
In the first half of 2015, the domestic intelligent hardware industry report showed that domestic smart hardware sales increased by 264% year-on-year, user volume increased by 215%, and smart hardware unit price increased by 50 yuan, including many health products. At the same time, many people think that health and smart devices must be based on the forefront of technology. The most basic function is to be able to accurately and effectively predict the price, while the price is within the personal tolerance. However, the equipment that can meet the accurate measurement is generally more expensive. At the same time, due to factors such as high appearance requirements, increasing R&D costs, unprofessional development platforms, and product testing failures, many smart hardware will be delayed.
At present, most of the health-related intelligent hardware has the function of measuring electrocardiogram or pulse monitoring. The extended measurement will be extended to the analysis of comprehensive data such as exercise, sleep, health, etc., through APP to understand your physical state to achieve the goal of initial health measurement. But at the same time, people are reserved for such wearable devices, because most of these products are large or consume a lot of power. Most of the hardware of such products include processors, sensors, communication connections, memory and other parts. The basic sensors include accelerometers, gyroscopes, magnetometers, etc. The communication connections may include Bluetooth, USB, RF and other multi-angle transmission connections. At the same time, such health devices also require basic security measures such as AES encryption. So the question is, how to ensure that the hardware is harmonious to play the optimal function while meeting low power consumption?
All in one Toshiba TZ1000 series
Key points for next-generation wearable devices: motion detection, context recognition, blood pressure measurement, skin resistance GSR (Galvanic Skin Response) monitoring, long battery life, and wireless charging. How to integrate these functions into one device and to satisfy the beautiful appearance is very important. The Toshiba TZ1000 Series application processor currently integrates Bluetooth® Low Energy (LE), low-power wireless communication standards, sensors, processors and flash memory. These features are tightly integrated into a single compact package, facilitating a miniaturized system design and reduced mounting area, making them ideal for small wearable devices. A single package can meet the appearance requirements of more healthy and intelligent hardware. At the same time, the application processor processes the data acquired by the sensor. The AFE dynamic performance guarantees energy saving and consumes only very low power, so it is suitable for long-term operation of the battery. Healthy wearable equipment.
TZ1000 Series Basic Application Low Power Example: In an active monitoring solution, a 100mAh battery can last for 86 days. Under the heart rate monitoring solution, the TZ10001 solution can be used for 7 days with 100mAh battery under high precision monitoring results.

In addition, the TZ1000 series can also be used to connect to external sensors, and developers can add additional sensors to their needs.

Toshiba Semiconductor's TZ1000 series integrates high-resolution ADCs that convert analog signals from external sensors (such as pulse waves and electrocardiograms) into digital data and transmit them to internal processors. High-performance ARM® Cortex with DSP The ®-M4F and floating point processing unit combines data from multiple sensors (internal and external sensors) for improved accuracy. The raw data and processed data are ultimately passed through the integrated Bluetooth® LE controller and RF circuitry to external devices such as smartphones and tablets. Currently, this series of products has been applied to wearable devices such as activity monitors, bracelet smart watches and eyeglass devices.
