Material Detail

Biomedical Electronics Explained: Medical Devices, Sensors & Healthcare Systems is a publication-grade Open Educational Resource (OER) module exploring the design, isolation, and clinical integration of biosensors, implantable devices, and diagnostic instrumentation.

Bridging cellular biophysics with precision electronic instrumentation, the curriculum investigates bio-potential sensing (ECG, EEG, EMG), biocompatibility standards (ISO 10993), electrical safety isolation (IEC 60601 Type CF), and closed-loop therapeutic systems (artificial pancreas, pacemakers, neural prosthetics).

Key Features:1. Interactive Signal Conditioning Simulator: A client-side JavaScript/Canvas engine modeling clinical ECG waveforms, 50/60 Hz mains interference, EMG muscle tremor artifacts, and active DSP filtering pipelines.2. Contemporary AI & Biophysical Computing: Rigorous integration of Physics-Informed Neural Networks (PINNs) with the Bidomain cardiac equations, Fourier Neural Operators (FNOs) evaluating Pennes' Bioheat transfer during ablation, and Lie-group SE(3) Invariant Extended Kalman Filtering (IEKF) for bionic prosthetics.3. Systems Architecture Trade-Offs: Comprehensive matrix contrasting wet Ag/AgCl vs. capacitive dry electrodes, optoelectronic vs. giant magnetoresistive (GMR) isolation, MICS vs. BLE telemetry, and primary batteries vs. transcutaneous resonant charging.4. Worked Numerical Design Application: Multi-step mathematical calculations detailing an active ECG front-end, quantifying 50/60 Hz displacement current, active Right-Leg Drive (RLD) gain sizing, and instrumentation amplifier CMRR attenuation.5. Curricular Assessment: 29 fully resolved review questions, analytical design scenarios, and numerical clinical problem sets in print-optimized collapsible details elements.
