Publication number: 20200315504Abstract: The invention includes method and materials designed to measure the material properties (e.g. thickness) of layers of material in a sensor using non-Faradaic EIS (Electrochemical Impedance Spectroscopy) methods. The methods are non-destructive, very sensitive and rapid. Typically in these methods, an AC voltage is applied to the desired material layer while the output current and therefore impedance is measured. This voltage can be applied in multiple frequencies in sweep mode in order to detect both the material and, for example, the thickness of the target material. In this way, EIS allows the characterization of properties of various layers of material disposed in devices such as electrochemical glucose sensors.Type: ApplicationFiled: April 4, 2019Publication date: October 8, 2020Applicant: MEDTRONIC MINIMED, INC.Inventors: Chi-En Lin, David Probst, Mohsen Askarinya, Akhil Srinivasan, Melissa Tsang, Michael E.

Patent number: 9252415Abstract: Arrays of planar solid state batteries are stacked in an aligned arrangement for subsequent separation into individual battery stacks. Prior to stacking, a redistribution layer (RDL) is formed over a surface of each wafer that contains an array; each RDL includes first and second groups of conductive traces, each of the first extending laterally from a corresponding positive battery contact, and each of the second extending laterally from a corresponding negative battery contact. Conductive vias, formed before or after stacking, ultimately couple together corresponding contacts of aligned batteries. If before, each via extends through a corresponding battery contact of each wafer and is coupled to a corresponding conductive layer that is included in another RDL formed over an opposite surface of each wafer. If after, each via extends through corresponding aligned conductive traces and, upon separation of individual battery stacks, becomes an exposed conductive channel of a corresponding battery stack.Type: GrantFiled: June 15, 2012Date of Patent: February 2, 2016Assignee: Medtronic, Inc.Inventors: Mohsen Askarinya, Andreas A.
