The fabrication and testing of a metallic micromachined fabric is presented. The fabric, similar in construction to chain mail, consists of small rings and links built upon a planar substrate and then released to yield a sheet that can bend along two axes and drape over curved surfaces. This micromachined fabric exhibits unique mechanical and electrical properties owing to the geometry and materials employed. Tests of electrical conduction under stress and mechanical failure strength are presented. Resistance of the chain mail is found to vary over nearly seven orders of magnitude under mechanical deformation. Combined with existing techniques, the new fabric holds promise to allow fully engineered smart textiles.
