Pilot experiments for biointerfacing: a (I) Cross section of biotesting well showing fluidic feed. a (II) Example of the interaction of epithelial cells (blue circles on the left) with vascular endothelial growth factors (yellow dots on the right) resulting in vasculogenesis excreted by the cells (red lines in the center). a (III) Printed testing platform in biocompatible resin (scale bar = 5 mm). b Temperature-stress-strain graph of the shape memory effect. c (I) Cross section of in-fiber SMA wires (scale bar = 1 mm). c (II) Side view of in-fiber SMA wires (scale bar = 1 mm). c (III) 5.2-mm segment of an in-fiber SMA wire in contraction after being heated at 80 °C. c (IV) 5.36-mm segment of extended in-fiber SMA wire at room temperature
