What to know about Stretchy, soft, and sticky: Advancing the next generation of wearable and implantable sensors

Researchers at Caltech, led by Professor Wei Gao, have developed two new bioelectronic advancements: a super-stretchy interface called SIRES for resilient sensing and a multifunctional implantable platform called ElHyX. These technologies aim to improve the stability and longevity of sensors attached to moving internal organs for the monitoring and treatment of chronic diseases.
