Adaptive concentrations are anothe major breathigh. Consider a valve that changes it orifice size based on fluid temperatur, without out any external electronics. By printing a valve from a shape-memory polimer that contracts or expands at a specific temperatur, accords can create a passive control system that reduces complecity and improwites replabiliability.
