Hypothesis
The study investigates the electromagnetic compatibility (EMC) of implantable neurostimulators with emissions from RFID emitters.
Conclusion
Most implantable neurostimulators were unaffected by RFID emissions, but one device showed significant effects at certain frequencies.
Supporting Evidence
- The study tested six neurostimulators against 22 RFID emitters.
- One neurostimulator showed inhibited output when exposed to 134 kHz RFID emitters.
- No effects were observed from other frequencies or devices.
Takeaway
This study looked at how well brain stimulation devices work near RFID readers, and found that most devices are safe, but one type had problems.
Methodology
Six active implantable neurostimulators were tested against 22 RFID emitters for electromagnetic interference.
Limitations
The study used a saline-filled phantom which may not represent real human conditions, and the configuration of devices was generalized rather than specific.
