Bidirectional Hyper-Connected Neural System (BHNS) concept and proof-of-concept semi-implantable devices. (a) Schematic representation of the envisioned BHNS. (b) Miniature electronic circuit for EMG sensing and stimulation and its comparison with a 1 cent euro coin for acute human demonstration of the BHNS concept. (c) Complete proof-of-concept semi-implantable device showing the dedicated insertion needle, the thin-film intramuscular electrodes, the thin guiding filament that exits through the needle hub, and the polymer capsule that houses the miniature circuit (opened lid) [17]
