Electrode foils suitable for use in electrolytic capacitors, including those having multiple configurations, have improved strength, reduced brittleness, and increased capacitance compared to conventional anode foils for electrolytic capacitors. According to one embodiment, the device includes a flexible belt capable of being encircled about a body part of an individual, and a strap attachable fixedly to the belt. The exhaust heat compensator is placed on the wafer guide and compensates exhausted heat from an edge area of the wafer. One or more catalytic ECL properties are generated by the interaction of the one or more conductive or redox active NPs and the liquid sample and measured at the one or more electrodes or with an optical detection system. A target physiologic event detector circuit can detect a target physiologic event such as an event of worsening HF using a comparison of the first and second transformed signal trends. At least one of the rotor portion 11 and the projections 13A is formed with cutout portions 13b at the boundary region between the rotor portion 11 and the projections 13A.
