CAPACITIVE MICRO-MACHINED ULTRASOUND TRANSDUCER CELL |
摘要 |
The invention relates to a capacitive micro-machined ultrasound transducer (CMUT) cell (6) comprising a cell floor (31) having a first electrode (7); a cell membrane (5) having a second electrode (7′) which opposes the first electrode and vibrates during transmission or reception of acoustic energy; a transmitter/receiver coupled to the first and second electrodes which causes the cell membrane to vibrate at an acoustic frequency and/or receives signals at an acoustic frequency; and an acoustic lens (13), overlaying the cell membrane, and having an inner surface opposing the cell membrane and an outer, patient-facing surface. According to the present invention the acoustic lens comprises at least one layer of a material selected from the group of: polybudatiene, polyether block amide (PEBAX), polydimethylsiloxane (PDMS) and buthylrubber. |
