<p>The present application relates to an ultrasonic device and associated method. The device includes a frequency generator configured to generate an oscillating signal having a predetermined frequency and power level. An ultrasonic transducer is configured to receive the oscillating signal and generate a mechanical vibration, wherein the frequency and amplitude of the mechanical vibration are controlled by the oscillating signal. A tool is configured to vibrate in response to the mechanical vibration, and at least one processor is configured to receive at least one operational characteristic relating to the vibration of the tool, and determine at least one property of material in contact with the tool using the operational characteristic in combination with predetermined values.</p> |
