Research output: Contribution to journalArticlepeer-review


Strategies are presented for achieving, simultaneously, both large areal coverage and high stretchability by using elastomeric substrates with surface relief in geometries that confine strains at the locations of the interconnections, and away from the devices. The studies involve a combination of theory and experiment to reveal the essential mechanics, and include demonstrations of the ideas in stretchable solar modules that use ultrathin, single junction GaAs solar cells.
