How can flexible sensors achieve long-term stability?

In implantable medical devices such as pacemakers and insulin pumps, the flexible temperature sensor of implantable devices has become the core component of postoperative monitoring due to its "biocompatibility+long-term stability" characteristics

H2: Special requirements for implantable device temperature measurement
H3: Biocompatibility (requires ISO 10993 cytotoxicity testing)
H3: Long term stability (no sexual decline for more than 5 years)
H3: Ultra thin and flexible (avoiding compression of surrounding tissues)
H2: Advantages of Implantable Scenarios for Flexible Sensors

H3: Long term stability: Accuracy still ± 0.6 ℃ after accelerated aging test (85 ℃/85% RH, 1000 hours)
A certain insulin pump manufacturer's implant test showed that the sensor drift over 5 years was less than 0.2 ℃, which is a reliable proof of the flexible temperature sensor for implantable devices.
H3: Anti tissue adhesion: Smooth surface treatment (Ra ≤ 0.1 μ m) to reduce fiber wrapping
H2: Practical Case: Lepu Medical Cardiac Pacemaker Project
Scenario: Lepu's new generation of leadless pacemaker (implantation site: right ventricle)
Solution: Customized 3 × 2mm flexible sensor (integrated into electrode wire)
Effect: The accuracy of temperature monitoring at 3 months after surgery was 99.2%, with no tissue inflammatory response
H2: Certification and Quality Assurance: "Trust Endorsement" for Implantable Sensors
Core certifications: ISO 10993 (biocompatibility), NMPA filing (Class II medical devices), FDA 510 (k) (optional)
Warranty policy: 5-year free replacement (industry average of 3 years), lifetime technical support
