EMI Shielding Design Considerations in Medical Application
This white paper explains the importance of EMI (electromagnetic interference) shielding in medical devices to ensure reliable performance and patient safety. EMI can disrupt electronic systems, especially with increasing use of wireless technologies. Effective design combines good signal integrity, grounding, filtering, and shielding techniques. Shielding must be applied at enclosure, module, and PCB levels, often using Faraday cage principles. Compliance with standards like IEC 60601-1-2 is essential for safety and regulatory approval. Various materials such as conductive elastomers, wire mesh, and metal components are used for shielding. Early integration of EMI control in design helps avoid failures, improve performance, and reduce development costs.
