The recent development of multimaterial fibers has enabled devices with unprecedented properties and functionalities. Here I present these fiber devices for biomedical and wearable applications. Current neural interface devices are mostly based on hard materials which can cause significant tissue damage. Using a thermal fiber drawing process, we have developed flexible multifunctional fibers for simultaneous electrical, optical and chemical communication with neural circuits in deep brain with minimal tissue damage. Moreover, flexible pressure sensors that can map pressure distributions is of great importance to various applications. Here we have developed a distributed pressure sensing fiber using frequency domain reflectometry. These fibers can also be woven into a fabric for pressure mapping applications such as touch pads, car seats, and wearables.
