conventional electromagnetic actuators, stack actuators have the following unique

• They can function at cryogenic temperatures or in environments with strong

• They can respond almost instantly to input with high rates of acceleration.

These actuators find their uses in proportioning valves, electrical relays, optical modulation, vibration dampening, and other applications requiring fast or precise

Piezoelectronic Transducers are often used in medical Ultrasound Equipment. Advances in equipment over the decades have enabled improved monitoring of pregnancies and facilitated minimally invasive surgical procedures (**Figure 6**).

• They only consume power when work is actually being performed.

• They can produce a large amount of force in a small package

• They can achieve extremely high degrees of precision.

### **3.6 Ultrasonic procedures**

Some non-invasive medical procedures rely on the use of focused ultrasonic waves to break up kidney stones or destroy malignant tissue (**Figure 7**). Additionally, the advent of the harmonic scalpel has enabled surgeons to simultaneously incise and coagulate tissue during a surgical procedure without the need for cauterization. This leads to less tissue damage, less blood loss, and faster healing times [13].
