Robots will be able to conduct a wide variety of tasks as well as humans if they can be given tactile sensing capabilities.

A KAIST research team has reported a stretchable, pressure-insensitive strain sensor by using a solution-based process. The process is easily scalable to accommodate large areas and can be coated as a thin film on three-dimensional, irregularly shaped objects via spray coating. These conditions make their processing technique unique and highly suitable for robotic electronic skin or wearable electronics applications.

Making - Skin - Tactile - Properties - Skin

The making of electronic skin to mimic the tactile sensing properties of human skin is an active area of research for applications such as wearable electronics, robotics and prosthetics. One of the major challenges in electronic skin research is differentiating external stimuli, particularly strain and pressure. Another issue is uniformly depositing electronic skin on three-dimensional, irregularly shaped objects.

To overcome these issues, the research team led by Professor Steve Park from the Department of Materials Science and Engineering and Professor Jung Kim from the Department of Mechanical Engineering developed electronic skin that can be uniformly coated on three-dimensional surfaces and distinguish mechanical stimuli. The new electronic skin...
