Flex PCB in Medical Device
The miniaturization of electronic circuits has become a major driver of innovation in medical technology, particularly in the development of medical device flex PCBs. Today, many hearing aids, medical implants, and other devices have strict requirements for electronic flex, which need to be installed in a small space. Flexible printed circuits produced by Flex Plus can be integrated into devices of almost any shape and space. Our ISO13485 certification ensures customers that our Flex PCB processes comply with the high standards expected from the market.
Hearing Aids
In hearing aid systems, the flexible circuit is not only used for internal interconnection but also functions as a miniaturized antenna for wireless signal transmission. The flexible circuit integrates RF antenna patterns with signal routing in an ultra-compact space, enabling stable Bluetooth or wireless communication while fitting the curved geometry of the ear. Its thin profile and controlled impedance design ensure reliable signal performance under continuous movement and long-term wear
Endoscope
For medical endoscopes, the FPC is designed with ultra-fine line width and spacing to support high-density signal transmission from imaging sensors and illumination modules. The precision circuitry enables stable high-speed data transfer within a very limited cross-section, allowing the endoscope to maintain a small diameter. The flexible structure withstands repeated bending during operation while ensuring electrical accuracy and signal integrity throughout the procedure.
Health Monitoring Wristband
In health monitoring wristbands, the flex PCB acts as the central flexible interconnect for sensors, battery, and wireless communication modules. It supports continuous acquisition and transmission of biometric data such as heart rate and motion while conforming to the wrist’s natural movement. The circuit is engineered for durability under frequent bending and skin contact, ensuring long-term stability and user comfort during daily wear.
Intravenous (IV) Drip Monitor

In IV drip monitoring systems, the FPC connects flow sensors, control electronics, and wireless communication modules for real-time infusion monitoring. The flexible circuit supports high-accuracy data transmission under mechanical stress and frequent handling. Its compact design allows integration into wearable or bedside monitors, enabling healthcare providers to track drip rates and patient status continuously and reliably.
Wireless Surgical (Dental) Loupes
Wireless surgical and dental magnifying loupes utilize a multilayer rigid-flex PCB to integrate imaging, illumination, power management, and wireless modules into a compact wearable system. The rigid sections provide mechanical stability for key components, while the flexible layers enable ergonomic routing and lightweight design. This rigid-flex structure ensures reliable electrical performance and structural integrity during prolonged surgical use without external cables.

Medical Smart Blood Glucose Test Module
The FPC in smart blood glucose test modules connects microfluidic sensors, signal processing chips, and wireless communication modules within a compact handheld device. High-density routing and precise trace design enable accurate data acquisition from tiny fluid samples. The flexible circuit ensures reliable signal transmission while allowing the device to maintain a slim, portable form factor for daily patient use.
