Overview
The AECG100 is a wearable-performance simulator that generates synchronized ECG and PPG analog signals for validation of wearable medical devices. It provides adjustable Pulse Wave Transit Time (PWTT) parameters, supports reflectance and transmittance PPG modules (green, red, infrared), and is intended for R&D, production-line and compliance testing. The system is designed to support IEC 60601-2-47, IEC 63203-402-3:2024, YY 0885 and YY 9706.247 workflows and includes GUI software, standalone operation and an SDK for automation.

Features

• Basic waveform outputs: ECG, sine, triangle, square, exponential, rectangular and triangle pulses with adjustable amplitude, timing and DC offset.
• ECG generation: pacing simulation, respiratory modulation, configurable noise, frequency/impedance testing and standards-compliant ECG waveforms.
• PPG generation: analog PPG for reflective or transmissive sensors with configurable LED wavelengths (green, red, infrared) and adjustable AC/DC levels for HR and SpO2 testing.
• Adjustable PWTT: simultaneous ECG and PPG output with programmable time differences (PTTp, PTTf) to validate BP and timing-dependent algorithms.
• SpO2 and R-curve simulation: reproduce R-curve shapes and perfusion-index ranges for SpO2 algorithm verification.
• Test parameter management: save and recall parameter sets for repeatable testing and reduced operator variability.
• Raw data playback: reproduce recorded clinical or custom waveforms for repeatability and validation.
• Assistant software and SDK: GUI workflows, automation SDK and editable auto-sequences for production and compliance testing.

Highlights

• High-resolution parameter control with DC offset capability; PI down to 0.025% (customizable).
• Standards support: IEC 63203-402-3:2024 (wearable PPG) and IEC 60601-2-47 (ECG).
• Raw clinical waveform playback for reproducibility.
• Standalone operation with storage for up to three parameter sets.
• Modular PPG options: reflectance or transmittance, single- or dual-optical modules to match DUT designs (smartwatch, ring, etc.).
• Custom fixtures and optical modules available to align DUT LEDs/PDs and improve measurement accuracy.
• SDK included for integration into automated test and production systems.
