A 2025 preprint described an open-loop tactile-classification experiment using human forebrain organoids. Event-based tactile data were encoded as electrical stimulation patterns and delivered through a microelectrode array. The organoid responses were then decoded by conventional analysis.
The authors reported average Braille-letter classification accuracy of 61% for a single organoid and 83% when responses from three organoids were combined. The work is useful because it tests a real sensor-derived tactile input.
