FREMONT, CA: Piezoelectric substrates, capable of generating an electric charge under mechanical stress, are gaining importance in various industrial fields, especially in medical technology. These materials, available in natural and synthetic forms, are transforming modern medical devices, increasing their efficiency and effectiveness.

Applications in medical devices

Ultrasound imaging

Piezoelectric substrates play an important role in ultrasonic imaging instruments. Closed crystals in ultrasound probes transform electrical signals into high-frequency sound waves that penetrate the body, reflect off organs and tissues, and generate complex images. This technology is crucial for non-invasive diagnostic methods, enabling real-time imaging and precise diagnosis.

Drug delivery systems

Piezoelectric substrates convert electrical signals into mechanical motion in drug delivery systems, controlling the rate and timing of drug release. Recent research has focused on creating piezoelectric micropumps that are compact, energy-efficient and reliable. For example, a silicon micropump that provides accurate dosing suggests prospects for miniature patch pumps for insulin delivery. These substrates guarantee precise and local drug release, enhancing the effectiveness of treatments.

Implantable devices

In implantable devices, piezoelectric substrates monitor vital signs and blood pressure fluctuations, facilitating early identification of health problems. Their advantages include biocompatibility and the ability to harvest energy by using biomechanical forces created by body movements to power the implants. This reduces the reliance on external batteries and spare parts, increasing patient convenience and reducing healthcare expenses.

Advantages of piezoelectric substrates in medicine

Piezoelectric substrates ensure precise and controlled drug delivery in medical systems, optimizing treatment outcomes. They produce and manage ultrasonic waves in ultrasound imaging, ensuring precise diagnostics. Their ability to sense pressure changes supports non-invasive medical procedures. Moreover, obtaining energy from these substrates enables the development of autonomous implants.

The unique ability of piezoelectric substrates to convert mechanical energy into electrical signals is expected to lead to breakthroughs in medical instrumentation.
