MonitorZ — Portable Dual-Channel ECG Measurement Device

Where This Shines

  • Not just another ECG recorder — it compares, analyzes, and understands signals in real time.
  • We built it for researchers who need clarity, control, and precision in every signal.
  • So we made it happen.

🤖 What Is MonitorZ?

MonitorZ is a portable, USB-powered ECG acquisition and analysis device designed for universities and research institutions developing and testing electrode technologies.

It features two fully independent acquisition channels: one for a reference electrode and one for the electrode under test, enabling direct performance comparison in real time.

The custom PC software receives continuous ECG data streams, applies filtering, and computes essential characteristics like amplitude, signal-to-noise ratio (SNR), channel correlation, and heart rate variability (HRV).

Together, these capabilities provide a research-grade platform for electrode evaluation and ECG signal analysis.

By enabling synchronized dual-channel measurement, MonitorZ brings precision and repeatability to ECG research workflows.

🫀 Problem

Testing and comparing ECG electrodes in research settings is often inefficient and fragmented:

  • Most systems record only one channel at a time
  • Comparisons require repeated, inconsistent measurements
  • Signal analysis tools are often separate from acquisition hardware
  • Setup is bulky and unsuitable for lab or classroom use

The result? Incomplete data, slow analysis, and limited reproducibility — making it hard to validate or improve electrode performance.

Types of quality in ECG signals

💡 Our Solution

We designed MonitorZ to make electrode evaluation accurate, synchronized, and simple. A compact, dual-channel ECG system with seamless PC integration — purpose-built for research.

  • Captures ECG signals from two electrodes simultaneously
  • Performs live filtering and feature extraction on the PC app
  • Computes SNR, correlation, amplitude, and HRV in real time
  • Requires no external amplifiers or complex calibration
  • Runs entirely via a single USB connection

With MonitorZ, researchers can test, compare, and refine electrode designs — instantly and repeatedly.
