From the past few years, the healthcare sector has witnessed a significant improvement in the design of medical equipment, along with better-streamlined functionality and performance. This, in turn, has improved the medical treatment methods. For example, piezoelectric transducers are used in ultrasonic dental scalers for ultrasonic removal of plaque and calculus, which is a more efficient method than traditional scalers. Similarly, piezoelectric ceramic components are increasingly being used in high-intensity focused ultrasound (HIFU) for the removal of tumors, as it is a minimally invasive and gentle treatment method with improved therapy success and fewer side effects in the human body.
