Latest Patents

Christa Dumschat holds a patent for a lead-free galvanic oxygen sensor. This sensor features an aqueous electrolyte and a bismuth anode, which is a significant advancement in sensor design. The electrolyte contains a polyol in addition to water and a salt, which surprisingly increases the sensor's resistance to passivation. This innovation leads to a sensor lifespan of over 100 days in some instances. The polyol can be added in amounts ranging from 20% to 30% and may include substances such as D-sorbitol, meso-erythritol, or glycerol. Notably, the inclusion of polyol in the electrolyte can extend the time until a sudden rise in potential for the sensor, while maintaining a constant current on the bismuth anode for more than 14 minutes.
