Instead Of ITO: Transparent EMC/EMI Shielding Film For Medical Devices Security

Transparent EMC/EMI Shielding Film For Medical Devices Security is a better choice. This EMI shielding film based on the Cu Mesh principle will allow hospital equipment to obtain better-shielding properties.

As an alternative to ITO technology, Transparent EMC/EMI Shielding Film For Medical Devices Security is ideal for protecting medical devices against electromagnetic interference (EMI). The product has been designed to fit any size and shape of medical device, including robots, diagnostic equipment, and portable devices.

What Kind Of Shielding Films Does Medical Devices Security Need?

Medical devices are a major concern for hospitals and other medical facilities. The devices themselves are expensive, and the cost of replacing them after a security breach can be catastrophic.

Some medical devices require sophisticated shielding films to reduce electromagnetic interference and radio frequency interference to the instrument. Generally speaking, the shielding films required by medical devices have the following common characteristics:

1. High resistivity:

Medical devices typically use high-frequency signals and high-voltage power supplies, which require conductive materials with large specific resistance.

2. High rigidity:

The shielding film should be very rigid to effectively shield microwave interference from outside sources.

3. High Conductivity:

The shielding film should be highly conductive in order to ensure that the device can still operate properly.

4. High-Temperature Stability:

The shielding film should have good temperature stability at high temperatures, which is often required by medical equipment used in sterilization processes.

Why not ITO technology?

ITO technology is one of the common technologies applied to thin films. This technology is based on the metallization of support with very thin layers. But its poor expressiveness makes it difficult to meet the higher needs of users:

• Provides lower conductivity: ITO technology has a conductivity of only 10-6 S/cm. This is not enough to meet the requirements of many applications, such as in high-power microwave devices or radar systems.
• Less opacity: ITO technology has a high degree of opacity, which makes it difficult for light to penetrate through the screen. It also results in poor visibility when using the device.
• Higher risk of oxidation: ITO technology has a high degree of oxidation, which makes it difficult to maintain the quality of the screen. The oxidation can be caused by exposure to oxygen and humidity.

Therefore, Micron has developed a Transparent EMC/EMI shielding film for Medical Devices Security that can replace ITO technology for these defects. It does not have the disadvantages of ITO technology but has advantages that ITO does not have.

What Is The Transparent EMC/EMI Shielding Film For Medical Devices Security?

What is the Transparent EMC/EMI Shielding Film?

Transparent EMC/EMI Shielding Film is a thin, transparent, and flexible conductive film that is composed of metal particles and polymer. It can be used to shield electric or magnetic fields in applications that require transparency such as displays and touch screens. The shielding properties of the film are derived from its conducting metal particles embedded in a nonconductive polymer matrix. The metal particles are typically composed of copper (Cu), silver (Ag), or nickel (Ni).

Electromagnetic wave shielding film is also called EMI (Electromagnetic Interference) protective film or absorbing material. The range of materials currently used as RFI (Radio Frequency Interference) shielding includes conductive metal oxides, metal meshes, and nanowire materials.

Micron’s EMI shielding film is mainly used to press on the film after the etching process of copper material. Such operations can reduce or eliminate electromagnetic interference and radio frequency interference to the internal circuits of the product, thereby achieving better shielding effects.

Structure Of The Transparent EMC/EMI Shielding Film For Medical Devices Security:

Micron’s Transparent EMC/EMI Shielding Film For Medical Devices Security is based on the Cu Mesh principle. It has good shielding performance, electrical conductivity, and light transmission.

Its structure is as follows:

Protective film (PE):

The protective film is made of high-quality PE material with good transparency, excellent mechanical strength, and flexibility. It can effectively protect the copper mesh from being damaged during transportation, storage, or installation.

Copper mesh:

Copper mesh has good electrical conductivity, heat dissipation, and shielding performance. This product is mainly used in electronic products such as mobile phones, laptops, and other devices that need to be protected against electromagnetic interference (EMI).

Substrate layer (PET):

The PET substrate has excellent mechanical strength, chemical stability, and heat resistance. It can effectively prevent the copper mesh from being damaged during transportation and installation.

Protective film (PET):

The bottom layer is still a layer of Protective film (PET), the same as the first layer mentioned above.

This Transparent EMC/EMI Shielding Film For Medical Devices Security has a very wide range of shielding functions, suitable for a variety of hospital equipment. It can provide perfect protection against electromagnetic interference and provide a safe environment for patients.

Copper Mesh Is Used In The Transparent EMC/EMI Shielding Film For Medical Devices Security:

As mentioned above, the disadvantages of ITO technology make it not suitable for shielding film. Micron’s Transparent EMC/EMI Shielding Film For Medical Devices Security uses copper mesh instead. This kind of copper mesh is very helpful when applied to Transparent EMC/EMI Shielding Film For Medical Devices Security:

• Copper mesh is a good conductor, which can reduce the resistance of the wire and make it easy for them to transmit electricity.
• Copper mesh is corrosion-resistant, and this makes it very suitable for use in medical devices. Copper mesh is also very flexible and can be bent easily (which is why it’s used in Transparent EMC/EMI Shielding Film For Medical Devices Security).
• The copper mesh can be made into various shapes according to the needs of different industries and products. This makes it more versatile than other materials, such as ITO film, which only has one shape.
• Copper mesh has a high melting point, which makes it more durable than ITO film and reduces the chance of the copper being damaged by heat or other factors.

Conclusion:

To sum up, the transparent EMC/EMI shielding film for medical devices security is a good choice to replace similar products of ITO technology. It perfectly makes up for the technical defects of ITO and provides better protection for medical device security.
