Wireless physiological sensor patches and systems

Abstract

The present invention provides methods, devices, and systems for wireless physiological sensor patches and systems which incorporate these patches. The systems and methods utilize a structure where the processing is distributed asymmetrically on the two or more types of ASIC chips that are designed to work together. The invention also relates to systems comprising two or more ASIC chips designed for use in physiological sensing wherein the ASIC chips are designed to work together to achieve high wireless link reliability/security, low power dissipation, compactness, low cost and support a variety of sensors for sensing various physiological parameters.
