Abstract: A lead frame for a current sensor is provided. The frame includes a conductive piece with an average thickness, and a sensing zone for generating a signal detectable by a current sensing element when current flows through the lead frame. It also includes a routing zone outside the sensing zone for routing current towards the sensing zone. The routing zone comprises a region with the largest area having a predetermined average thickness. At least the sensing zone includes additional material disposed on the conductive piece so the total thickness of the sensing zone is thicker than the average thickness of said largest area.

A conformal layer is provided by atomic layer deposition between the first substrate and the second substrate, thus protecting at least the sensing element from discharge from the second substrate.

Abstract: A device for synthesis of macromolecules is disclosed. In one aspect, the device comprises an ion-releaser having a synthesis surface comprising an array of synthesis locations arranged for synthesis of the macromolecules. The ion-releaser also includes an ion-source electrode, which is arranged to contain releasable ions and is arranged to be in contact with each of the synthesis locations of the synthesis surface, thereby release ions to the synthesis locations. The ion-releaser further comprises activating electrodes, which are arranged to be in contact with the ion-source electrode, wherein each one of the activating electrodes is arranged in association with one of the synthesis locations via the ion-source electrode. The ion-releaser is arranged to release at least a portion of the releasable ions from the ion-source electrode to one of the synthesis locations, by activation of the activating electrode associated with the synthesis location.

Abstract: A method for coating a conductive polymer onto a cathode-active material for an ion insertion-type electrode comprises: providing an at least partially oxidized cathode-active material having an intrinsic electrode potential, and contacting a precursor of the conductive polymer with the at least partially oxidized cathode-active material. The precursor has a polymerization reduction potential that is lower than the intrinsic electrode potential of the at least partially oxidized cathode-active material, thereby electrochemically polymerizing the precursor onto the cathode-active material.
