Brief introduction

In the field of medical electronic devices, the performance of materials is crucial for the reliability, safety, and effectiveness of the equipment. PET (polyethylene terephthalate) silver plated film, as an important functional material, is gradually being widely used in medical electronic devices. Advanced Institute (Shenzhen) Technology Co., LtdPET silver plated filmThe research and application promotion of related technologies play a positive role. This article will delve into the anti-corrosion and conductive properties of PET silver plated film in medical electronic devices.

2、 Characteristics of PET silver plated film

1. Basic characteristics of PET film
   • PET film itself has good mechanical properties, such as high tensile strength and toughness, which enables it to maintain structural integrity in different processing and usage environments. Meanwhile, PET film has good chemical stability and a certain tolerance to many chemicals, which provides a basic guarantee for its application in medical electronic devices.
   • It also has the advantages of high transparency and strong processability, and can be customized according to the specific needs of medical electronic devices, such as cutting, forming, and other operations.
2. Characteristics of silver plating layer
   • Silver is a metal with excellent conductivity, second only to gold and copper. After silver plating on the surface of PET film, the conductivity of the material can be significantly improved. This is a crucial characteristic for components in medical electronic devices that require electrical signal transmission, such as electrodes, sensors, etc.
   • Silver also has natural antibacterial properties, which is an additional advantage in medical environments. Although this article mainly focuses on its anti-corrosion and conductive properties, antibacterial properties indirectly have a positive impact on the hygiene and safety of medical electronic devices.

3、 The anti-corrosion effect of PET silver plated film in medical electronic equipment

1. Form a physical barrier
   • In medical electronic devices, many components are exposed to environments containing various chemicals, such as disinfectants, body fluids, etc.PET silver plated filmThe silver plating layer in can serve as a physical barrier to prevent these chemicals from coming into direct contact with the protected substrate material, such as the metal parts of electronic components. The dense structure of the silver layer can effectively prevent the invasion of external substances, thereby reducing the occurrence of corrosion.
   • For example, in some implantable medical electronic devices, such as pacemakers, the metal electrodes and circuit parts of the device need to work in the human body fluid environment for a long time. PET silver plated film can be wrapped around the surface of these components to prevent corrosion of metal parts by substances such as salt and protein in body fluids, thereby extending the service life of the equipment.
2. Electrochemical Protection
   • Silver has a relatively positive position in the electrochemical sequence and can act as a cathode when in contact with other metals, such as some of the more active metal components that may exist in medical electronic devices, providing cathodic protection for the more active metals. This electrochemical protection mechanism can effectively suppress the corrosion reaction of metals.
   • Advanced Institute (Shenzhen) Technology Co., LtdResearch has shown that by optimizing the preparation process of PET silver plated film, the effectiveness of this electrochemical protection can be further improved. For example, precise control of the thickness and uniformity of the silver plating layer can ensure stable corrosion protection in different medical electronic device usage scenarios.

4、 The conductive effect of PET silver plated film in medical electronic devices

1. Electrode and sensor applications
   • In medical electronic devices, electrodes and sensors are very important components. For example, in electrocardiogram (ECG) devices, electrodes need to accurately detect weak electrical signals from the human body and transmit them to the device for analysis. The high conductivity of PET silver plated film makes it suitable for use asElectrode materialOr the covering layer of the electrode to ensure efficient transmission of electrical signals.
   • For biosensors, such as sensors that detect physiological indicators such as blood glucose and blood oxygen, PET silver plated film can provide a good conductive pathway to ensure accurate signal transmission between the sensor and external detection circuits. Advanced Institute (Shenzhen) Technology Co., Ltd. has conducted extensive research on the development of new electrodes and sensors based on PET silver plated film, continuously improving their conductivity and signal detection sensitivity through improved coating technology and composite with other functional materials.
2. Electromagnetic shielding and anti-interference
   • Medical electronic devices are susceptible to external electromagnetic interference during operation, and the devices themselves may also generate electromagnetic radiation, affecting the normal operation of other devices. The conductivity of PET silver plated film enables it to act as electromagnetic shielding.
   • When PET silver plated film is applied to the shielding layer of the outer shell or internal circuit of medical electronic devices, it can effectively reflect and absorb external electromagnetic radiation, while also preventing electromagnetic signal leakage inside the device. This helps to improve the electromagnetic compatibility of medical electronic devices and ensure stable operation in complex electromagnetic environments. Advanced Institute (Shenzhen) Technology Co., Ltd. has found through experimental research that reasonable designPET silver plated filmThe layout and structure of medical electronic devices can maximize their electromagnetic shielding effect.
