High-precision Micro Detection Coil for Oximeter & Heart Rate Monitoring Devices

Portable oximeters and heart rate monitors are civil health monitoring devices that rely on micro precision induction coils to collect and convert physiological data such as blood oxygen concentration and heart rate. As precision health instruments, they require supporting coils to have micron-level dimensional accuracy, zero batch deviation, low hysteresis and high signal stability. Ordinary micro coils have poor winding accuracy and inconsistent parameters, causing detection data drift and excessive error, failing medical precision calibration standards and restricting product marketization.

Our client specializes in R&D of portable household health monitoring equipment, with products compliant with domestic and EU medical device certification standards. The original micro coils had delayed signal response and large parameter deviation, resulting in unstable detection data and failed precision calibration. The client needed zero-deviation, low-hysteresis and high-sensitivity micro detection coils to meet medical-grade precision monitoring requirements.

Fuying Electronics adopts medical-grade low-hysteresis magnetic materials and micron-level CNC winding technology to accurately control coil turns, impedance and dimensions, realizing zero batch parameter deviation. The optimized ultra-compact structure adapts to miniaturized portable equipment design. Full-process precise calibration and layered inspection eliminate defective products with parameter errors. All coils pass medical-grade precision calibration and low-power durability tests to ensure stable and accurate signal collection.

With our customized coils, the client’s health monitoring devices achieve stable and accurate detection data with zero excessive error, fully passing domestic and international medical certification. Product credibility and market competitiveness are significantly improved. Fuying Electronics provides high-precision, zero-deviation customized micro coils for various portable medical and health monitoring devices.
