AI-Enabled Digital Stethoscope

01

Overview

CoBuild Labs partnered with a healthcare innovator to develop a next-generation digital stethoscope that combines high-fidelity heart and lung sound acquisition with multimodal physiological sensing and AI-powered analysis. Designed for clinicians, telemedicine providers, and remote patient monitoring, the device delivers clinical-grade auscultation in a compact, ergonomic, and portable form factor.

02

The Challenge

The client envisioned a modern digital stethoscope that went beyond traditional auscultation. The key objectives included:

• Capture high-quality heart and lung sounds with minimal ambient noise.
• Integrate multiple biosensing modalities into a single handheld device.
• Enable AI-assisted analysis for improved diagnostic support.
• Design a compact and ergonomic product suitable for everyday clinical use.
• Support seamless connectivity for telemedicine and remote healthcare applications.
