Randomized trial demonstrates a new RF exposure system for electrophysiological measurements using microelectrode arrays, suggesting improved study of bioelectromagnetic effects.
Key Points
This study aims to develop and characterize a dual-band RF exposure system for real-time electrophysiological recordings.
Designed and integrated a dual-band RF exposure system operating at 0.7 GHz and 3.5 GHz using a Localized Radiating-End Coaxial line (LoREC).
Performed full-wave COMSOL simulations to evaluate field confinement and specific absorption rate (SAR) distributions.
Assessed compatibility with microelectrode array (MEA) devices to analyze electrophysiological recordings under RF exposure.
Achieved stable impedance matching with effective confinement of the electromagnetic field in the biological target area.
SAR analysis revealed frequency-dependent exposure patterns, consistently distributed across the electrode area.
