Miniaturized Soft Transformable Swimmer for Evironmentally Friendly and Sustainable Fluidic Carrier

We developed a magnetically actuated soft transformable microswimmer for an environmentally friendly and sustainable fluidic handling. They are made of the composite mixture of magnetic micro particles and soft UV curable resin. The custom developed manufacturing system allows to program the local magnetizations of each fractional areas with UV light exposure for both the bending motion by magnetic field and the surface microstructuring to minimize surface stiction. The manufacturable device scale ranges from the smallest of 38S×702 µm

to the largest 2.0×5.5 mm

. We demonstrated successful liquid sample handling between droplets or hydrogel substrates showing a great potential to serve as a fluidic carrier for biochemical sample analysis or drug delivery.
