摘要： In k31 mode, a vibration is along an axis or orthogonal to the poling or electric field orientation. The direction of vibration is toward a face of an ultrasound transducer array. For each element of the array, electrodes are formed perpendicular to the face of the array, such as along the sides of the elements. Piezoelectric material is poled along a dimension parallel with the face of the transducer and perpendicular to the direction of acoustic energy propagation. Using elements designed for k31 resonant mode operation may provide for a better electrical impedance match, such as where small elements sizes are provided for a multi-dimensional transducer arrays. For additional impedance matching, the elements may be made from multiple layers of piezoelectric ceramic. Since the elements operate from a k31 mode, the layers are stacked along the poling direction or perpendicular to a face of the transducer array for transmitting or receiving acoustical energy.

摘要： Matching layers are provided, including: electrically conductive acoustic matching layers, methods for conducting electric current through matching layers, methods for manufacturing multi-dimensional arrays using conductive matching layers, and multi-dimensional arrays with electrically conducting matching layers. Matching layers with conductors aligned for providing electrical conduction through the thickness or range dimension of the matching layer are provided. For example, vias, aligned magnetic particles, or conductive films at least partially or entirely within the matching layer of each element allow electrical conduction from the transducer material to a ground foil or flex circuit. By using multiple electrical conductive matching layers, a gradation in acoustic impedance for better matching is provided while allowing dicing of the entire stack, including the matching layers and the electroceramic material, in one step.

摘要： One or more conductors within a transducer or element are anodized and/or electrochemically etched for electrical isolation. Anodization allows for simultaneous creation of many insulation layers on a selective basis. Electrochemical etching allows for simultaneous creation of many electrode gaps on a selective basis, which can be later filled with insulating material such as epoxy. Conductors may then be plated over the anodized material for interconnecting other conductors or electrodes together.

摘要： A capacitive membrane is used as a digital sensor. Membranes act as binary devices, such as being in a collapsed or non-collapsed state. By providing drum heads (membranes and associated gaps) with different response characteristics, the drum heads of an element digitally indicate the amplitude of the acoustic force by which of the drum heads are triggered or change states. The digital transducer may be used for different types of sensors, such as a CMUT, an air pressure, a temperature, a humidity, a chemical or biological stimulus or other sensor.

摘要： Electrical connection is provided in a transducer stack through a backing block. A flexible circuit is sandwiched between pieces of acoustic attenuating material. For example, 2 to 200 or more flexible circuits are stacked in alternating layers with pieces of acoustically attenuating material. The alternating layers are then connected together to form a backing block with Z-axis electrical connection. The top surface of the connected backing block includes a plurality of exposed electrical traces from the flex circuit. Since flex circuits are used, the electrical traces are precisely aligned along one dimension. Since pre-formed acoustic attenuating material pieces are used, precise alignment is provided along a second or orthogonal dimension. The substrate holding the electrical traces in the flexible circuits provides more stability and allows for easier connection to circuit boards as compared to individual strips of metal.
摘要翻译：通过背衬块在换能器堆叠中提供电气连接。柔性电路夹在声衰减材料片之间。例如，2到200个或更多个柔性电路以交替的层与多个声衰减材料堆叠。然后将交替层连接在一起以形成具有Z轴电连接的背衬块。连接的背衬块的顶表面包括来自柔性电路的多个暴露的电迹线。由于使用柔性电路，所以电迹线沿着一个维度精确对准。由于使用了预先形成的声衰减材料片，所以沿着第二或正交的尺寸提供精确对准。与单个金属条相比，在柔性电路中保持电迹线的基板提供更多的稳定性并且允许更容易地连接到电路板。
