A wearable healthcare device can be defined as a non-invasive system that can self-monitor or support specific medical functions. The term "wearable" indicates that the device is either a device that is worn directly on the human body, or a piece of clothing, and has a suitable design to support its use as a wearable accessory. Broadly speaking, this requires the device to be extremely small in size and weight, functionally autonomous, self-contained, easy to use, and comfortable to wear.
Smart wearable healthcare devices and typical architectureThere are many types of smart wearable healthcare devices, such as wristbands, watches, glasses, and other wearable types. Functions performed include pedometer, heart rate monitoring, motion recording, biopotential measurement, bioimpedance measurement, oximetry, and more.
Smart wearable healthcare devices are an extension of traditional medical devices. Common hospital medical devices are large in size, complex in structure, and high in power consumption, and are intended for high-precision clinical applications. With the development of sensors and semiconductor technology, device size and power consumption are much smaller than before, making wearable devices a reality. Many of the technologies used in hospital clinics have moved from hospitals to homes or to various wearable devices.
Smart wearable healthcare devices are often non-invasive vital sign monitoring devices that are easy to use and wear. In order to enhance the user experience, the lighter the weight, the lower the power consumption, the better. It also provides connectivity to other consumer electronics devices.
Size is very important. Most wearable devices are light and smaller and smaller
Smaller package
Advanced packaging technology to increase integration
I hope that the fewer external components, the better.
Ultra low power consumption
Power consumption is critical to the user experience, the lower the better
Limited battery size due to system size
Low quiescent current chip facilitates low power consumption and extended standby time
Wearable devices typically require a low-power MCU
Wearable devices require low power connection technology
Ergonomic design
Easy to use
Prevent misoperation design
Highly reliable, highly sensitive sensor design
High reliability
Adapt to various environments
Good mechanical design to prevent equipment damage
Sometimes the device needs to be waterproof
Sensor Technology
Multi-sensor fusion
Choose sensor materials with good biocompatibility
High sensitivity at low power consumption
Connection technology
Need low-power Bluetooth, WIFI connection to access other smart devices
Data synchronization and application auto-upgrade
ADI offers a wide range of highly integrated AFEs, motion sensors, low-power MCUs and power management solutions to optimize the quality and reliability of wearable devices.
Eye protection:The principle of chlorophyll defocusing is adopted to prevent the eyeball from focusing for a long time, effectively alleviate eye fatigue, and achieve better eyesight protection.
Anti-blue light, ultraviolet light:The Green Light Film can actively filter the target wavelength while providing a band in the range of 380-400nm. It can effectively block 100% harmful light.
Edge coverage:The soft material fully covers the edges of any device, so it can be affixed to curved screen and round edges, 100% provides excellent edge coverage, and there is no gap between the edges of the device.
Oleophobic and waterproof:The oleophobic coating surface of the Green Light Screen Protector can provide your phone with oleophobic and waterproof properties, which can prevent sweat, grease residue, and fingerprints.
Sensitive touch:The 0.14mm ultra-thin film does not interfere with the touch response, almost as if it does not exist. When using a mobile phone, the fingertips can be easily swiped, bringing you a comfortable gaming experience.
