Abstract: The invention relates to a non-contact printing method and system as well as to a printed sensor. The method includes the steps of disposing a substrate (130) between a discharge electrode (110) and a printing material (140) such that the substrate (130) is spaced apart from the printing material (140); and activating the discharge electrode (110) to generate an electric field between the substrate (130) and the printing material (140), wherein the printing material (140) moves onto a surface (132) of the substrate (130) when the electric field attracts the printing material (140) to the surface (132) of the substrate (130). A corresponding printing system and printed sensor are also provided.

Abstract: A multi-walled carbon nanotube thin film can be manufactured and operatively attached to a fabric for use with immobilized patients to sense when one or more body parts of an immobilized patient experiences prolonged pressure. A boundary of the multi-walled carbon nanotube thin film can be equipped with a plurality of electrodes that can be injected with current. Voltage measurements can be taken which can be translated into changes in impedance throughout the multi-walled carbon nanotube thin film. The changes in impedance, in turn, are representative of points and magnitudes of pressure experienced by the multi-walled carbon nanotube thin film as a result of the one or more body parts of the immobilized patient contacting and exerting pressure on the multi-walled carbon nanotube thin film.
