MIT engineers build soft sheet that senses its own shape
Engineers at MIT have made a soft, stretchable sheet with zig-zagging optical fibres that reconstructs its own shape as it bends and twists. The study appears in the peer-reviewed journal Advanced Intelligent Systems.
Graduate student Qifan Yu, graduate student Nina Cao and assistant professor Kaitlyn Becker built the fibres from a clear rubber core with one roughened side. An algorithm reads how the light changes as the fibres bend. The sheet still rebuilt its shape accurately when a few fibres were cut or disconnected. The team suggests uses in physical therapy, gaming and robot control, but these uses have not been tested yet.
