Thinness

Definition

Thinness refers to the physical property of having a small thickness or being lightweight. In the context of flexible and stretchable circuits, thinness is essential as it enables the integration of electronic components into various substrates while maintaining comfort, flexibility, and wearability for users. A thinner design also reduces the overall weight of devices, enhancing their usability in wearable technologies.
