Soft lithography-based techniques for microdevice fabrication. A. Microcontact printing can be utililized for fabrication of microdevices in regions of contact of PVA with micropillar stamp with subsequent dissolution of PVA in water for device release [59]. B. Fabrication of microdevices from recessed regions of microwell stamp. The stamp was brought into contact with glass to remove PPMA from non-microwell regions before bringing the remaining PPMA into contact with PVA [59]. C. Discontinuous dewetting utilized to selectively collect resin before UV-induced polymerization. Microdevices were then brought into contact with PVA with subsequent dissolution in water for device release. [56]. Adapted with permission.
