Abstract: To provide a foilboard, in particular an e-foil, which can be ridden by a rider in a seating position and which has a good controllability and is save to use, a foilboard, in particular e-foil, is proposed comprising a board and a hydrofoil, the hydrofoil comprising a mast and at least one wing, wherein the mast is attached to an underside of the board, wherein the foilboard further comprises a seating device for a ride to sit on, wherein the seating device is arranged on a top side (18) of the board, such that the seating device can be rolled at least in a forward direction and in a backward direction by the rider to control and/or steer the foilboard.

Abstract: A method for forming a microstructure is disclosed in which, after a polymer substance has been applied to a first substrate, the first substrate is micromachined to remove at least one portion of the first substrate. A second substrate is then adhered to the first substrate via the polymer substance. One application of such a method is in the fabrication of three-dimensional microfluidics. The polymer substance may, for example, be benzocyclobutene (BCB), and the first substrate may, for example, be a silicon wafer or a photo-etchable glass.
