| 摘要 |
The invention relates to a device for determining properties of a medium, having a carrier (2) which can be brought into contact with the medium (3); at least one transmitter (4), arranged on the carrier (2), for exciting acoustic waves (A) in the carrier (2); at least one receiver (5), arranged on the carrier (2), for receiving acoustic waves (A, A′) which originate from waves (A) excited in the carrier (2) by means of the transmitter (4); a first material region (61) arranged on the carrier (4); and a second material region (62) arranged on the carrier (4), wherein the name of the second material region (62) is such that it absorbs sound waves at the frequency of the acoustic waves (A) excited in the carrier (2) more strongly than the first material region (61). The invention also relates to a method for producing such a device. |
