New method to fabricate 3D curvy electronics
We report a manufacturing technology, called conformal additive stamp (CAS) printing and show that it can be used to reliably manufacture electronic devices with 3D shapes. Our CAS printing approach employs a pneumatically inflated elastomeric balloon as a conformal stamping medium to pick up pre-fabricated electronic devices and print them onto 3D surfaces to create devices with curvy shapes including electrically small antennas, hemispherical solar cells and smart contact lenses.
