2026 Shielding Solution for Medical IoT Devices to Prevent Electromagnetic Interference from High-Frequency Electrosurgical Units
The world of medical technology is rapidly evolving, driven by advancements in the Internet of Things (IoT). Medical devices are becoming increasingly connected, enabling healthcare professionals to monitor patients remotely and provide more accurate diagnoses. However, this increased connectivity also brings new challenges, particularly when it comes to electromagnetic interference (EMI) from high-frequency electrosurgical units (ESUs).
Electrosurgical units are used in various surgical procedures, including laparoscopic surgeries, cardiothoracic surgeries, and neurosurgeries. These devices generate high-frequency electrical currents that can interfere with nearby medical IoT devices, causing malfunctions or even patient harm.
To mitigate this risk, the development of effective shielding solutions is crucial. Shielding materials and technologies are being researched and developed to protect medical IoT devices from EMI generated by ESUs. This report provides an exhaustive analysis of the current state of shielding solutions for medical IoT devices, focusing on their ability to prevent electromagnetic interference from high-frequency electrosurgical units.

3. Emerging Shielding Technologies
Researchers and manufacturers are exploring new shielding technologies to improve the effectiveness of EMI protection in medical IoT devices.
a) Active Shielding
Active shielding involves using an active device, such as an amplifier or oscillator, to generate a signal that cancels out the incoming EMI. This approach has shown promise in reducing EMI levels by up to 30 dB.
Table 3: Comparison of Shielding Technologies
| Technology | Effectiveness (dB) |
|---|---|
| Passive Shielding | 10-20 |
| Active Shielding | 20-40 |
| Hybrid Shielding | 30-50 |
b) Hybrid Shielding
Hybrid shielding combines passive and active shielding techniques to achieve improved EMI protection. This approach has shown significant promise, with some studies indicating a reduction in EMI levels by up to 50 dB.
4. Market Analysis and Forecast
The market for shielding solutions is growing rapidly, driven by the increasing adoption of medical IoT devices and the need for effective EMI protection.
