This work is an innovative health monitoring product that focuses on chronic disease management, sports health and other scenarios, and integrates microneedle technology and intelligent sensing. Aiming at the pain points of traditional blood sampling detection, such as strong invasiveness and single monitoring index of existing wearable devices, relying on micro-electromechanical system (MEMS), electrochemical sensing and low-power wireless communication technology, the trinity core architecture of "minimally invasive microneedle patch wireless data terminal health management APP" is constructed to realize the health management closed loop of "painless sampling, multi-index synchronous monitoring and real-time data analysis. In the design of the microneedle sensing module at the core of the hardware, the length of a single microneedle is only 400 μm, the diameter of the patch is 2cm, and the thickness is 1mm. The density of 200 microneedles/cm is used to balance painless experience and high-efficiency liquid collection. The material is medical grade degradable polylactic acid (PLA) and medical silicone, and the surface is coated with hydrophilic anti-sweat coating and skin repair coating to minimize skin irritation. The module has a built-in three-electrode system, which synchronously and accurately detects the four core physiological indicators of glucose, lactic acid, uric acid and electrolyte through the differentiated "biometric element/sensitive membrane electrode combination" design. Glucose, lactic acid, uric acid detection based on redox reaction to generate current signal, sodium, potassium ion detection based on ion selective response to generate potential signal, and then through the 4-channel independent processing module amplification, filtering, to ensure that the signal without crosstalk. The wireless data terminal adopts 1.5-3V low-voltage multi-channel independent power supply. Through ARM Cortex-M low-power microprocessor and "multi-mode signal conversion algorithm", the electrical signal is converted into concentration value, and 12 hours of encrypted historical data are classified and stored. In transmission, Bluetooth 5.0 BLE is used as the main channel, and multi-index data is packaged and transmitted 1-2 times per second, with a delay of less than 1 second and a full power endurance of 7-10 days. NFC is used to realize 1-second fast pairing between mobile phones and terminals, taking into account both real-time and convenience. The health management APP is equipped with a multi-indicator data analysis engine. The main interface uses a "four-quadrant card design" to visually present real-time values and dynamic curves, and sets exclusive early warning thresholds for different indicators. The innovative addition of AI linkage analysis function can generate comprehensive health reports across indicators, and provide personalized suggestions in combination with sports, chronic disease management and other scenarios. At the same time, it supports data export and sharing to doctors to help multi-dimensional health assessment and accurate diagnosis and treatment. In addition, it also optimizes interactive functions such as voice broadcast and one-click report for the elderly to reduce the use threshold. The product can be widely used in chronic disease management of diabetic patients, diet control of gout patients, scientific training and supply guidance for athletes, health monitoring of the elderly living alone and home rehabilitation monitoring of postoperative patients. It not only solves the problems of "pain, lag and single detection" in traditional monitoring, but also promotes the upgrading of health management from "single index control" to "multi-dimensional balanced management", with both technical innovation and social practical value.
