Liquid Droplet Stamp Transfer Printing

Despite the increasingly significant role of flexible electronics in information, energy, and medical treatment, their integration with a special‐shaped interface remains an unresolved challenge. The traditional transfer method, as a core technology of device integration, is still unsuitable for thinned chips and 3D sensors. Solid‐contact elastomer stamp sometimes causes cracks while non‐contact method such as sacrificial layer method fails to...
