Abstract

To improve the sensitivity of an ultrasound sensor device 1 used for detecting an object e.g. a car reversing aid, the ultrasound sensor device 1 has a multiplicity of ultrasound sensor elements 3a, b. Each ultrasound sensor element 3a, b comprises a basic body or substrate 4 with an opening 5a, b, a flexible bending element 6a, b, which closes a first end of the opening 5a, b. The flexible bending element 6a, b may be a polymer, particularly a liquid crystal polymer, but metals or metal oxides are also proposed. The piezoelectric element 7a, b, is arranged in the opening 5a, b in contact with the flexible bending element 6a, b and a damping element 8a, b closes the second end of the opening 5a, b. An array of these transducers makes use of a single or unitary substrate 11 (fig 2). The flexible bending element 6a, b may be integral with the substrate 4 (fig 3).
