Wearable cardiac ultrasound patch, cardiovascular disease identification system, and method thereof

Abstract

A wearable cardiac ultrasound patch, a cardiovascular disease identification system, and method thereof integrate a silicon photonic integrated circuit layer with a microelectromechanical integrated circuit layer into an optical fiber micro-sensor, which is encapsulated with a computing chip as a single unit. This allows the examinee to perform cardiac ultrasound detection and processing in a wearable and convenient manner, free from time or geographic constraints. The silicon photonic elements in the silicon photonic integrated circuit layer and the piezoelectric elements in the microelectromechanical integrated circuit layer are stacked and arranged in a two-dimensional array, enabling the wearable cardiac ultrasound patch to scan at more angles. Furthermore, the cardiovascular disease identification system of the present invention can process the examinee's cardiac ultrasound signals, electrocardiography (ECG) signals, and phonocardiography (PCG) signals. These three data types cross-validate one another, improving the detection rate of comprehensive cardiovascular diseases and reducing the time and misdiagnosis rate for physicians diagnosing cardiovascular diseases.
