Abstract: A method for fabricating crystalline surface structures (4) on a template (1). The method comprises the steps of providing a template (1) into a reaction environment, wherein one or more elements (3) required for the formation of the crystalline surface structure (4) are contained within the template (1); heating the template (1) inside the reaction environment to increase the mobility of the element (3) within the template (1), and to increase the surface diffusion length of the element (3) on the template-environment interface; and activating the template (1) by altering the conditions within the reaction environment, to make the mobile element (3) slowly migrate towards the template-environment interface and to make the element (3) organize on the surface of the template (1) as a crystalline structure (4).

Abstract: A touch sensor having a touch sensitive film, a signal filter, electrical circuitry and a processing unit. The film is capable of capacitive or inductive coupling to an external object when a touch is made by the object. The signal filter is formed by the resistance of the film and the capacitive or inductive coupling to the external object, and the filter has properties affected by location of the touch and/or capacitance or inductance of the touch. The electrical circuitry is coupled to the touch sensitive film and configured to supply excitation, amplitude and wave form into the signal filter and to receive response signals from the signal filter. The processing unit is configured to detect the presence or proximity of a touch, the location of said touch, the capacitance and/or inductance of said touch by processing response signals and thereby measuring changes in the properties of the signal filter.
