Title: Ju-yi Chen: Inventor Advancing Wearable Cardiac Monitoring

Introduction

Ju-yi Chen is an inventor associated with National Cheng-Kung University in Tainan, Taiwan. His patent work focuses on cardiovascular monitoring and methods for detecting arrhythmias using wearable sensors and image-based signal reconstruction. His portfolio includes 2 patents.

Latest Patents

Chen’s work includes a wearable cardiac ultrasound patch and a cardiovascular disease identification system. The invention combines silicon photonic and microelectromechanical components in a compact sensor unit with a computing chip. Its two-dimensional sensor array supports cardiac ultrasound scanning from multiple angles, while the system processes ultrasound, electrocardiography (ECG), and phonocardiography (PCG) signals. Cross-checking these signals is intended to support more comprehensive cardiovascular assessment and help reduce diagnostic time and misdiagnosis.

Another invention describes a method and system for reconstructing ECG signals from images for arrhythmia detection. It analyzes skin color changes associated with heartbeats to derive a remote photoplethysmographic signal, extracts relevant frequency and time-domain features, and combines them to reconstruct an ECG waveform. The waveform can then be assessed for characteristics associated with arrhythmias.
