Abstract: A system includes a conformable biopotential sensor that withstands a defibrillation pulse. The conformable biopotential sensor includes a polymer substrate, a plurality of electrodes printed on the polymer substrate, a signal trace printed on the polymer substrate, and one or more resistors printed on the polymer substrate and in electrical communication with an electrode of the plurality of electrodes via the signal trace. One or both of the one or more resistors and the polymer substrate withstand a defibrillation pulse. The conformable biopotential sensor further includes a coating layer applied to the one of both of the one or more resistors, wherein the coating is more thermally conductive than the polymer substrate.

Abstract: A method and miniaturizable device is described to read/write information to an optical storage medium (11). A device comprises one or more light sources (12) bounded up with an access unit (10) which is arranged to be controllable to a position, in which light beams (21, 22) are transmitted transversal towards an optical storage medium, and reflected light beams (33) are analysed by a detector element (18, 26) which further informs the access unit whether to move or stand still to keep light beams in focus and on track. A device according to the invention is possible to implement in a small size and low weight due to reduced component count and thin access unit geometries. A communication device (80) according to the invention may be implemented to fulfil a crucial need for ultraminiature range of communication devices.
