Suitable for wearable health monitors (blood glucose, blood pressure, heart rate), portable ultrasound probes, medical infusion sensors, rehabilitation therapy devices and medical IoT data acquisition modules, with core characteristics of miniaturization, low power consumption, high sensitivity, biological compatibility and portability. It supports multiple low-power communication protocols (Bluetooth 5.3, LoRa, 5G medical version) to realize real-time transmission of patient data to medical terminals; the circuit has excellent moisture and corrosion resistance, adapting to long-term wear and outdoor medical scenarios, and maintains stable signal transmission under dynamic movement and temperature changes.
Use low-noise high-sensitivity sensor signal processing circuits to improve data acquisition accuracy (error ≤0.5% FS) and anti-interference ability; adopt ultra-low-power control chips and energy management circuits to extend the battery life of wearable devices to 7-15 days under field conditions; integrate multi-sensor (heart rate, blood oxygen, temperature) signal acquisition and processing circuits in one module, reducing the number of components and failure points; use flexible PCB (FPC) for compact wiring of wearable devices, adapting to the curved surface of the human body; adopt three-proofing (waterproof, sweat-proof, dust-proof) circuit packaging technology, reaching IP65~IP67 protection level, and use biological compatibility materials for skin-contacting components to avoid allergic reactions.
Wearable blood glucose monitors use high-precision electrochemical sensing circuits to achieve accurate blood glucose detection (±0.3mmol/L error), supporting real-time monitoring for diabetic patients; portable ultrasound probes rely on compact signal processing circuits to realize clear imaging of internal organs, adapting to emergency medical scenarios; medical infusion sensors use stable drive circuits to monitor infusion flow in real time, with alarm accuracy up to 99.9%, preventing infusion errors; rehabilitation electrical stimulation devices integrate low-noise stimulation circuits to achieve precise adjustment of current intensity, improving rehabilitation efficacy and patient comfort.
Miniaturized and high-density circuit processing increases production difficulty, and the yield of complex flexible circuits is about 87-89%; wearable medical devices need long-term reliability verification (≥5 years) and biological compatibility testing, extending R&D cycles; harsh use environments (sweat, humidity, movement) easily cause circuit interface failure, requiring additional sealing and anti-corrosion processes; the market has high requirements for product cost performance, and it is difficult to balance high precision, low power consumption and low price for mass-produced wearable medical electronics.
