Abstract: The invention is a wrist worn Photoplethysmography Sensor (“PPG”) and Pulsed Electro Magnetic Field (“PEMF”) integrated into a thin ergonomic wristband. The invention will measure heart rate, oxygen saturation, and heart rate variability. In addition to PPG measurements, the PEMF generator treats a user's blood with an electromagnetic field tailored to the individual. The electromagnetic field washes red blood cells and/or erythrocytes and/or any other vertebrate organisms which principal means of delivering oxygen and other cellular nutrients to the body tissues via blood flow through the circulatory system for optimal CELLHEALTH™.

Abstract: An electrotherapy electrode device. A generally thin, flexible top layer includes an aperture. A terminal is adjacent the top layer. The terminal has a generally planar shoulder, a post projecting from the shoulder, and a generally planar contact surface opposing the shoulder. The terminal includes a magnetic material. The post of the terminal extends through the aperture of the top layer and the shoulder of the terminal contacts the top layer.
