Paragraph starter
The principle of unidirectional transition waves in bistable lattices, as demonstrated by Nadkarni et al. (2016), offers a valuable insight for designing systems with controlled wave propagation. By engineering asymmetry into the bistable elements, a mechanical diode effect can be achieved, enabling waves to travel in a single, predetermined direction. This has significant implications for impact absorption and signal transmission in advanced materials.
