A non-aqueous isotropic electrically conductive signal receptive composite is disclosed comprising a continuous conductive material, with a top surface and a bottom surface with both surfaces substantially covered by a dielectric polymer material with a polar material within the dielectric polymer.

[Problem] Provided is an electronic functional member of superior wear resistance. [Solution] The present invention comprises a fiber network constituted by a water-soluble resin and a poorly water-soluble resin, and an electroconductive member formed on the fiber network. The water-soluble resin and poorly water-soluble resin are, for example, polyvinyl alcohol derivatives. In accordance with an embodiment of the electronic functional member according to the present invention, the fiber network is formed by layering a first fiber network constituted by fibers containing a water-soluble first resin and a second fiber network constituted by fibers containing a poorly water-soluble second resin. Alternatively, the fiber network may be constituted by fibers containing the water-soluble first resin and fibers containing the poorly water-soluble second resin. Alternatively, the fiber network may be constituted by fibers containing the water-soluble first resin and the poorly water-soluble second resin.

Systems and methods for a medical device are provided. The handheld medical device includes a housing including a front and rear side. A diaphragm is located in the center of the rear side of the housing. Three or less rear electrodes, configured to collect electromagnetic signals from the chest region of a patient, are located in a semi-circular in shape that encircles the diaphragm on the rear side of the housing. Two front electrodes located on the front side of the housing collect signals from the left and right index fingers of the patient. A screen is located between the two front electrodes. The device may include a transmitter, in some cases a Bluetooth module, for coupling the medical device to a user device. The user device includes an application that receives the signals and performs analysis on them. The five electrode inputs are used to calculate seven ECG channels.
