Researchers at the University of California, Santa Barbara have developed new methods for the design and fabrication of stretchable electronic devices that can achieve high integration densities, similar to those that can be achieved using conventional PCBs. This technology produces complex stretchable electronic devices based on a wide variety of thin polymer substrates. Strain relief geometries and features allow these stretchable devices to integrate widely used surface mount devices (SMDs) in complex circuits that may be miniaturized. The process provides sufficient control over geometry to enable the use of automation tools including optical registration and robotic components assembly. This technique is compatible with existing industrial manufacturing processes, making it a scalable solution for manufacturing stretchable electronics. Early demonstrations of this technology have delivered high signal-to-noise ratio physiological measurements of peripheral hemodynamics, confirming its suitability for health monitoring applications, but many other applications are possible.
