Thin film materials have many advantages in terms of properties, applications and economic considerations. Stretchable thin films have been shown to have promising applications in optical gratings, precision metrology and stretchable electronics. Figure shows a Silicon based integrated circuit that is stretchable, twistable and foldable. Bending of circuits to an extreme folded state is not possible by conventional flexible electronics. Stretchable electronics opens up many new opportunities and possibilities in design and application as compared to rigid electronics – for example in the biomedical area, energy harvesting, energy storage and wearable electronics.
Figure shows use in biomedical applications which is not possible with standard rigid electronics - an electronic eye camera with dynamically tunable zoom, eye cameras inspired by anthropod eyes, device integrated on rabbit heart, multifunctional balloon catheter integrated with sensors, actuators and other components. These systems were shown to provide very stable electronic performance.
