Multi‐channel wireless mapping of gastrointestinal serosal slow wave propagation

High‐resolution (HR) extracellular mapping allows accurate profiling of normal and dysrhythmic slow wave patterns. A current limitation is that cables traverse the abdominal wall or a natural orifice, risking discomfort, dislodgement or infection. Wireless approaches offer advantages, but a multi‐channel system is required, capable of recording slow waves and mapping propagation with high fidelity.
