Abstract: The present invention relates to a body electrode for recording electrophysiological signals from a body. In particular the invention relates to a body electrode (100; 200; 400) comprising a transducer element (105; 205) shielded by a layered shield structure (120; 220; 420) and a skin contact element (115; 115?; 115?; 215) providing a contactbetween the layered shield structure (120; 220; 420) and the skin (101; 201) of the body. The layered shield structure (120; 220; 420) comprises at least an electrically conducting layer (113; 213) and an electrostatic dissipative layer (112; 212; 412). The skin contact element (115; 115?; 115?; 215) comprises an electrically onducting layer (113; 213) and an ion conducting layer (114; 214) and is with regards to the electrical potential characteristics matched with a transducer element (105; 205).

Abstract: A method of urine flow measurement where liquid in the form of a free-fall jet is collected in a collecting vessel and the vertical force produced by the collecting vessel on a measuring device, for example a scale or the like, is sensed, and the change in time of said force is utilized for obtaining a measure of the flow corresponding to the jet. The method is especially characterized in that the effect of the impulse of the jet on the sensed force is eliminated by deflecting the vertical flow constituted by the jet to a substantially horizontal flow by a rotating device before the liquid is caused to contact the vessel. The invention also relates to a flow meter.
