Abstract

Systems and methods are provided that integrate control electronics with a wireless on-board module so that a conformal ultrasound device is a fully functional and self-contained system. Such systems employ integrated control electronics, deep tissue monitoring, wireless communications, and smart machine learning algorithms to analyze data. In particular, a stretchable ultrasonic patch is provided that performs the noted functions. The decoded motion signals may have implications on blood pressure estimation, chronic obstructive pulmonary disease (COPD) diagnosis, heart function evaluation, and many other medical monitoring aspects.

Description

[0001] Cross References to Related Applications [0002] none Background technique [0003] It is known to measure blood pressure in various ways. The standard method is to use a blood pressure cuff. Alternative and more advanced methods have also been developed. [0004] For example, PCT / US2018 / 013116 titled "Scalable Ultrasound Transducer Device" describes a skin-integrated conformal ultrasound device capable of non-invasively acquiring central blood pressure (CBP). The system requires the ultrasound patch to be connected to a background data acquisition system. While useful, it has the disadvantage of requiring this data coupling. [0005] This background is provided to introduce a brief background to the Summary and Detailed Description that follow. This background is not intended to aid in determining the scope of the claimed subject matter, nor is it considered to limit the claimed subject matter to implementations that solve any or all of the disadvantages or probl...
