The application further relates to a method of protection a portable device against corrosion and to the use of a portable device. An object of the present application is to protect selected metallic parts of a bodyworn electronic device against corrosion in a flexible and controlled manner. The problem is solved in that the portable device includes a sacrificial anode in the form of a component adapted to be surface mounted on the substrate. This has the advantage that corrosion can be contained at a specific location. The device may e.g. be used for portable listening devices, e.g. hearing aids or headsets or earphones including a part adapted for being worn at or in an ear of a user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Use of a sacrificial anode for corrosion protection of a portable device, e.g. a hearing aid","description":"A portable device includes a substrate, a number of electronic components, and a battery having an anode and a cathode for energizing at least some of the components.
