Programmable Materials (Technology).
In engineering and design, Exoskin describes a 'programmable material' that acts like a smart, shape-changing skin.
What it is:
A material made of a soft, flexible silicone base covered with hard triangular shapes.
How it works:
By using air to inflate or deflate specific parts of the material, it can change its physical shape to create bumps or textures.
Why it's used:
It is primarily used to give objects a way to change how they feel, such as letting a steering wheel send a physical feeling (like vibration or shape) to the driver for navigation without distracting them.
