摘要
En 中文
The incorporation of electronics onto curved surfaces promises to bring new levels of intelligence to the ergonomic, aesthetic, aerodynamic, and optical surfaces that are ever-present in our lives. However, since many of these surfaces have 2D (i.e., nondevelopable) curvature, they cannot be formed from the deformation of a flat, nonstretchable sheet. This means that curved electronics cannot capitalize on the rapid technological advances taking place in the field of ultrathin electronics, since ultrathin devices, though ultraflexible, are not stretchable. In this work, a shrink-based paradigm is presented to apply such thin-film electronics to nondevelopable surfaces, expanding the capabilities of current nondevelopable electronics, and linking future developments in thin-film technology to similar developments in curved devices. The wrinkling of parylene-based devices and the effects of shrinkage on common electrical components are examined, culminating in shrinkable touch sensors and organic photovoltaics, laminated to various nondevelopable surfaces without loss of performance.
