Linktop’s TrueBP™ Smart Ring Passes Clinical Validation, Advancing Cuffless Blood Pressure Monitoring with ECG, AI, and Continuous PPG

Linktop, a leading digital health and wearable technology company, today announced that its next-generation TrueBP™ Smart Ring has successfully passed multi-center clinical validation.

Built on years of R&D, the device enables continuous, cuffless blood pressure monitoring using Pulse Transit Time (PTT), while integrating medical-grade ECG, AI-powered cardiac analysis, and continuous Photoplethysmography (PPG) sensing into a single wearable form factor.

A Breakthrough in Continuous Blood Pressure Monitoring

Traditional blood pressure measurement relies on cuff-based devices, limiting frequency and real-world insights. Linktop’s TrueBP™ technology leverages PTT—measuring the time it takes for a pulse wave to travel through the vascular system—to estimate blood pressure continuously.

By combining ECG and PPG signals with personalized calibration models and AI algorithms, the smart ring delivers real-time blood pressure trends throughout the day without user intervention.

⸻

Clinically Validated Accuracy and Stability

In multi-center clinical studies, the TrueBP™ Smart Ring was benchmarked against medical-grade reference devices, demonstrating:

• Accuracy for both systolic and diastolic blood pressure within international standards

• High stability during long-term wear

• Strong consistency across resting and daily activity scenarios

These results validate the feasibility of PTT-based blood pressure monitoring in wearable devices.

Multi-Modal Sensing: ECG + AI + Continuous PPG

The TrueBP™ Smart Ring integrates three core health monitoring technologies:

Medical-Grade ECG with AI Analysis

• Single-lead ECG acquisition

• AI-driven detection of cardiac abnormalities

• Early screening capabilities for cardiovascular risks

Continuous PPG Monitoring

• 24/7 heart rate tracking

• Blood oxygen and circulation trends

• HRV and stress insights

• Sleep and recovery analysis

PTT-Based Blood Pressure Estimation

By synchronizing ECG and PPG signals, the system enables continuous blood pressure monitoring beyond traditional point measurements.

Proven Global Regulatory Track Record

Linktop has established a strong global compliance foundation. Multiple vital-sign monitoring devices from the company have received certifications from:

• U.S. Food and Drug Administration (U.S.)

• CE marking (CE Medical, Europe)

• Therapeutic Goods Administration (TGA, Australia)

This regulatory experience supports the company’s expansion into global healthcare markets.

Toward Continuous, Preventive Healthcare

The TrueBP™ Smart Ring represents a shift from episodic measurement to continuous, passive health monitoring, offering:

• Cuffless, all-day blood pressure tracking

• Integrated ECG and AI-based cardiac insights

• Continuous PPG-based physiological monitoring

• Applications in hypertension management, telehealth, and preventive care
