The video shows ultrasonic powering of a fracture monitor demonstrator.
In the video, the experimental setup is shown. At the start, the function generator, connected to the RF amplifer are shown. They generate the driving signal to the transmitting transducer (cylinder in the water tank). The demonstrator (gray box in front of the transmitting transducer) is ultrasonically powered and connects via Bluetooth to a smartphone app. The ultrasonic receiver are pre-charged collapse-mode CMUTs. The experiment is performed in a tank filled with de-ionised water. The data measured by the strain gauge (at the bottom of the demonstrator housing) is processed and transmitted via Bluetooth. In the video, a piece is removed from the demonstrator: it is a switch to enable the Bluetooth communication. The application shows the data collected by the strain gauge, when vibrations are created in its structure by tapping on the table of the experimental setup.
