Provided are systems and methods for the post-treatment of dry adhesive microstructures. The microstructures may be post-treated to comprise mushroom-like flaps at their tips to interface with the contact surface. In some aspects, a change in material composition of the microstructures in a dry adhesive may affect mechanical properties to enhance or diminish overall adhesive performance. For example, conductive additives can be added to the material to improve adhesive performance. In other aspects, microstructures comprising conductive material may allow for pre-load engagement sensing systems to be integrated into the microstructures.

A mechanical metamaterial comprising a chiral structure and a reentrant structure repeatedly layered to form a 3D structure with improved compressive response is disclosed. The 3D structure of the present invention is a metamaterial which can be perfectly and easily produced by a photocuring 3D printing process without any internal support. The introduction of modified carbon nanotubes into the printing composite material improves the compression resistance and impact resistance of the products and increases the service life through the special periodic structure. The application of 3D printing technology in fabricating mechanical metamaterials can break through the processing limitation of traditional processing technology or microelectronics manufacturing technology to make three-dimensional periodic structures.
