How are electronics used in medicine and biology?

In the field of biomedical engineering, electronics are essential for designing devices that diagnose, treat, and manage diseases. This interdisciplinary field integrates engineering principles with medicine and biology to improve patient care.1

Diagnostic and Imaging Technologies

Electronics power advanced medical imaging systems that visualize internal structures:
* Magnetic Resonance Imaging (MRI): Uses powerful magnets and electronic pulse sequences to detect hydrogen oscillations, creating detailed anatomical images.2
* Computerized Tomography (CT): Employs electronic detectors to measure X-ray photons from multiple angles, which a computer reconstructs into cross-sectional images.3
* Microfluidic systems: Often called "labs-on-chips," these portable units integrate electronic and mechanical components to perform rapid biochemical assays.4

Therapeutic and Monitoring Devices

Electronic components are critical for active medical interventions:
* Transcranial Magnetic Stimulation (TMS): Uses electromagnetic induction to discharge electric currents through coils, creating magnetic fields that stimulate brain neurons for treating psychiatric disorders.5
* Bioinstrumentation: Includes devices like pacemakers and heart monitors. Modern prosthetics now incorporate microprocessors and sensors to provide tactile feedback and mimic natural movement.16
* Wearable Technology: Devices such as smartwatches use integrated electronics to monitor heart rate and blood pressure in real time.1
