Abstract: A pollen paper formed from a plurality of pollen microgels, which paper is dimensionally locked for use in the generation of conventional printed matter. It is possible to remove the printed subject matter from the pollen paper by a process that involves immersing the pollen paper into an alkaline bath, then removing the water through immersing it in a dehydrating bath and finally dimensionally locking the paper by immersing it in an acidic bath.

Abstract: Disclosed herein is a hygromorphic composite material comprising a moisture-active pollen paper substrate formed from a plurality of pollen microgel particles, and at least one moisture-inactive layer applied onto the top and/or bottom surface of the moisture-active pollen paper substrate with a pattern that causes the hygromorphic composite material to change its shape in a pre-determined manner due to a change in relative humidity of its ambient environment. Also disclosed herein is a method of forming the hygromorphic composite material.

Abstract: The present invention provides a four-chain six-degree-of-freedom hybrid mechanism. The four-chain six-degree-of-freedom hybrid mechanism comprises a fixed platform, a sliding rail mounted on the fixed platform, two sliding blocks, a mobile platform and four linear actuator chains connecting the mobile platform with a first sliding block and a second sliding block. The mobile platform is square-shaped. In the four linear actuator chains, the first linear actuator chain and the third linear actuator chain have the same structure while the second linear actuator chain and the fourth linear actuator chain have the same structure. The mobile platform can achieve six degrees of freedom. The four linear actuator chains coordinate to drive so as to achieve two translational degrees of freedom and two rotational degrees of freedom; the first sliding block and the second sliding block coordinate to drive so as to achieve the other translational and rotational degrees of freedom.
