Medical electronics is a branch of biomedical engineering focused on the design, development, and application of electronic devices for medical use. It encompasses instrumentation, imaging systems, monitoring equipment, therapeutic devices, implantable electronics, and the processing of biomedical signals.

The field has evolved from early electrocardiography and fluoroscopy to complex digital systems. Advances in microelectronics, sensors, and signal processing enabled portable monitors, integrated circuits, and wireless communication, expanding capabilities in diagnosis, treatment, and research.

Core technologies include biosensors and electrodes, analog and digital electronics, data acquisition, signal conditioning, and software. Power management and biocompatible packaging are critical for implantable and wearable devices. Safety and interoperability are ensured by standards and regulatory requirements.

Applications include diagnostic and monitoring equipment such as ECG and EEG systems, ultrasound and imaging hardware; implantable therapies such as pacemakers, defibrillators, deep brain stimulators, and cochlear implants; external stimulators such as electrical neuromodulation devices; and hospital equipment like infusion pumps and anesthesia monitors.

Safety and regulation: Medical electronics devices are governed by standards such as IEC 60601-1 for medical electrical equipment, and regulatory pathways including FDA clearance in the United States and CE marking in the European Economic Area. ISO 14971 guides risk management; cybersecurity and electromagnetic compatibility are continuous concerns.

Future directions include continued miniaturization and wireless, batteryless and energy harvesting implants, advanced biocompatible materials, sensor fusion and artificial intelligence for diagnostics and therapy, enhanced remote monitoring, and stronger emphasis on interoperability, safety, and data privacy.
