All living organisms have systems that can link multiple signals to manage tasks. For example, humans have systems of organs that can combine inputs from sight, hearing, and smell in a fear response that can cause our hearts to speed up. This ability—called complex signal integration—is not found in artificial systems. This new study demonstrates a pathway for simple, soft artificial materials to use multiple signals from external sources to produce distinct responses. ...
