1. Project Background
Smart wearable devices are a general term for devices designed and developed with wearable technology for daily use, such as: smart watches, smart bands, smart glasses, etc.. At the same time, smart wearable devices are also an important application scenario of Internet of Things technology, allowing for a more intelligent and efficient lifestyle through wireless connections and network interactions.
With the rapid development of technology,integrated medical and elderly care health smart wearable devices have already become a part of our lives; the Ministry of Industry and Information Technology, the Ministry of Civil Affairs, and the National Health and Family Planning Commission issued the “Smart Health Elderly Care Industry Development Action Plan (2017-2020)” which proposed the use of AI, Internet of Things, big data and other information technology means to promote smart health elderly care application system integration, connecting various levels of medical institutions and elderly care service resources, establishing a dynamic monitoring mechanism for elderly health, integrating information resources, and providing smart health elderly care services for the elderly. Let’s look forward to medical smart wearable devices bringing health blessings to more people!
The editor introduces a design plan for a smart wearable device based on ESP32 (for learning and exchange purposes only):
2. Hardware Resources
1) ESP32-S3 serves as the core controller, responsible for complex computations and interaction processing, defaulting to 8M Psram + 32M flash combination
2) HC32L110C6UA is the auxiliary processor, responsible for handling low-power tasks
3) LSM6DSL six-axis posture sensor, low power consumption with multifunctionality
4) QMC5883L three-axis magnetometer, combined with LSM6DSL can achieve nine-axis posture fusion
5) BMP280 barometer, capable of measuring altitude and environmental temperature
6) CW2015 coulomb meter, accurately counting battery power
7) A 1.28-inch round screen with 240*240 resolution and capacitive touch screen
8) Vibrator
9) 3.85V lithium battery charging and discharging management, protection
3. Hardware Design Scheme
1) Lithium Battery Charging and Discharging Module
2) Various Sensor Modules for Smart Watch
3) Smart Watch MCU Core Control Module
