Abstract
Methods of fabricating ultra-miniature, ultra-compliant probe arrays through spin coating, wherein a dissolvable material in hydrogel form is dispensed onto an assembled mold with wires. Once the dissolvable material is dispensed onto the mold, centrifuging spin casts the material by evaporating the solvent, forming a dried dissolvable polymer. Finally, a device is used with water to remove excess dissolvable material to obtain a dissolvable needle with wires.
