A mold tool includes: a first tool part and a second tool part that works together with the first tool part. In the closed state, the two tool parts are moved toward one another, and in the open state, the two tool parts are moved away from one another. The mold tool also includes a first mold half in the first tool part and a second mold half in the second tool part. The two mold halves reshape the sheet of material, arranged between the two tool parts, into at least one three-dimensional article when the two tool parts are moved toward one another. The mold tool also includes a cutting device including at least one cutting element and at least one actuating device. The actuating device extends the cutting element in the direction of the sheet of material, to cut the sheet of material.

The present disclosure provides a method for preparing a piezoresistive sensor material, including: preparing a wood fiber aerogel; conducting dopamine self-polymerization on the surface of the aerogel to obtain a wood fiber-based hydrogel; soaking the wood fiber-based hydrogel in a nano conductive phase suspension or a nano conductive phase precursor to form a conductive phase-loaded wood fiber-based hydrogel; subjecting the conductive phase-loaded wood fiber-based hydrogel to reaction with an aqueous solution including a polyelectrolyte monomer, a crosslinker, an initiator and a catalyst to form a conductive phase-wood fiber-based hydrogel composite; and complexing the composite with metal ions. The present disclosure further discloses a piezoresistive sensor including the sensor material, and a preparation method thereof. The sensor material prepared by the method of the present disclosure has excellent mechanical strength and ionic conductivity, and a sensor further prepared has extremely-high sensitivity.
