Stretchable electronics with mechanical properties compatible with biological systems enable emerging applications such as continuous physiological monitoring, neural sensing and modulation, and programmable mechanoreceptors is disclosed. Here, we introduce a physical sacrificial layer strategy that significantly accelerates and simplifies the fabrication of stretchable electronics. By using poly(vinyl alcohol) (PVA) as a physical sacrificial layer, devices can be rapidly released through manual peeling followed by direct contact etching in 2 minutes irrespective of the area. This approach not only offers exponential speed improvements over traditional methods but is also broadly applicable to existing stretchable electronics fabrication processes. Furthermore, it enables vertical interconnect access (VIA) and interposers to integrate diverse electronic components, modules, and systems on different scales. To demonstrate its versatility, we demonstrate stretchable circuits featuring integration between soft circuit, surface mount components and human interaction underscoring its potential for rapid implementation of sophisticated heterogeneously integrated stretchable electronic systems.
