Flexible electronic circuits mimicking the sensory capabilities of biological skin are being developed to restore the sense of touch in artificial limbs and robotics. This focus discusses the mechanical and electronic performance that electronic skin must reach to make a substantial impact in these applications.
Tactile sensors provide robots with the ability to interact with humans and the environment with great accuracy, yet technical challenges remain for electronic-skin systems to reach human-level performance.
This Review discusses the materials and electronic requirements for flexible sensors and electronic systems to mimic the mechanical and sensing properties of natural skin, with the goal of providing artificial prostheses with sensing capabilities.
