The present disclosure relates to a non-invasive and continuous biomedical detections and non-invasive and continuous monitoring methods and devices for extracting and analyzing interstitial fluid extracted non-invasively and continuously from the skin of a subject comprising non-invasively electroporating the skin using a non pulsed voltage in combination with a pulsed voltage and applying negative pressure.

Non-invasive biomedical detection and monitoring systems

The invention relates to polycomponent electrocatalysts suitable for use at the cathode of electrochemical and fuel cells. More particularly, the invention relates to a polycomponent electrode comprising a catalytic electrode including a mixture of a metallic component including at least one metal selected from palladium, platinum, ruthenium, rhodium, iridium or osmium and a chemical component including at least one compound selected from the group consisting of suitable oxometallates and metallic acids. Preferably, the metallic component comprises at least one metal selected from the group consisting of platinum and palladium and the chemical component comprises at least one compound selected from the group consisting of tungstic acid, molybdic acid, ammonium tungstate, ammonium molybdate, sodium tungstate and sodium molybdate. The electrode is operable in fuel cells which employ readily available oxygen or air.

Electrocatalysts for H.sub.2 /O.sub.2 fuel cells cathode

The present invention is concerned with a ternary alloy electrocatalyst for oxygen reduction in fuel cell electrodes or other catalytic structure. The electrocatalyst of the present invention is made of a noble metal chromium-copper alloy supported on an electrically conductive material, and has a mass activity for oxygen reduction at least four times higher than that of unalloyed noble metal.
