Ultrasound device contacting |
abstract |
An ultrasound device comprises a transducer arrangement and an acoustically transmissive window over said arrangement, said window comprising an elastomer layer having conductive particles dispersed in the elastomer, the elastomer layer having a pressure-sensitive conductivity. An electroactive material actuator is provided for biasing the transducer arrangement towards the transmissive window. The electroactive material actuator is controlled in dependence on a measured pressure-sensitive conductivity. In this way, a feedback system is provided for controlling a contact pressure. The device can be implemented with low cost and with low power consumption. |
