High frequency ultrasonic transducer and matching layer comprising cyanoacrylate
First Claim
1. An ultrasonic transducer stack, comprising:
- a plurality of layers comprising;
a piezoelectric layer;
at least one matching layer that comprises a first matching layer, which comprises cyanoacrylate; and
a lens layer comprising TPX,wherein each layer of the plurality of layers has a top surface and an opposed bottom surface, wherein the first matching layer is connected to and underlies the bottom surface of the lens layer, and wherein the piezoelectric layer underlies the bottom surface of the matching layer.

Abstract
In one aspect, matching layers for an ultrasonic transducer stack having a matching layer comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In another aspect, the matrix material is loaded with a plurality of heavy and light particles. In another aspect, an ultrasound transducer stack comprises a piezoelectric layer and at least one matching layer. In one aspect, the matching layer comprises a composite material comprising a matrix material loaded with a plurality of micron-sized and nano-sized particles. In a further aspect, the composite material can also comprise a matrix material loaded with a plurality of heavy and light particles. In a further aspect, a matching layer can also comprise cyanoacrylate.
