EMI Design Considerations for Medical Applications Whitepaper

Electromagnetic interference (EMI), also known as radio frequency interference (RFI), is when an outside source causes noise or interference in an electrical path or circuit. Shielding is necessary to help prevent EMI from causing electronic devices to malfunction. Such malfunctions can range from the innocuous — an odd noise on a car radio — to the serious — an accident related to failing safety equipment.

The significant advancement in electronic devices, particularly in communication and wireless technology, has led to a substantial increase in electromagnetic interference (EMI). These unwanted signals not only compromise the efficiency of equipment but also can disrupt the operation of communication systems. One example is microprocessors, which use high-frequency signals in their operation and can cause nearby equipment to malfunction if these high-frequency signals are allowed to escape and impact other
components inside or in close proximity to the device.

This paper aims to give engineers a look at what technological advances will challenge current approaches to EMI shielding and provides a detailed overview of the materials currently on the market.
