Wearable Flexible Electronics

Wearables refer to electronic devices worn on the body, implanted within the body, or even tattooed on the skin. This includes footwear, bodywear, wristwear, eyewear, headwear, microchip implants, and even injectable smart tattoos [1].

While not all wearables are inherently flexible, they constitute a significant proportion of flexible electronics. These devices incorporate components like flexible screens, flexible batteries, and flexible integrated circuits — they conform to body movements without causing discomfort or losing electrical conductivity.
