Abstract: A hydrogel-cement composite material, wherein, including following raw materials in parts by weight: 99.5-99.98 parts of a cement, 0.02-0.5 parts of a strengthening hydrogel, and 80-100 parts of a water; and the strengthening hydrogel is prepared by adopting a method including following steps (1)-(5): in the step (1), uniformly mixing a polyvinyl alcohol solution and a sodium alginate solution, and stirring in an ice-water bath; and in the step (2), adding a cement hydration product phase-dispersion liquid of nano-ettringite whiskers, and uniformly stirring; and in the step (3), adding a calcium chloride solution, and carrying out a cross-linking reaction; and in the step (4), crushing and drying a cross-linking product to obtain solid particles; and in the step (5), soaking the solid particles in a mixture solution of a glutaraldehyde and a hydrochloric acid to obtain the strengthening hydrogel after soaking.

Abstract: A force sensor comprising a contact arrangement for transmitting a contact force to a force sensor assembly. The force sensor assembly comprising a first sensor sensing, and producing an output from, a normal contact force component of the contact force; and a body moveable on transmission of the contact force to the force sensor assembly; and a second sensor for sensing, and producing an output from, a relative displacement of the body relative to the second sensor, the a tri-axis contact force being determined from the relative displacement.
