Typical soft PZT characteristics include:

· Wide range of frequencies in transmit and receive (sub-audible, audible, ultrasonic)

· High output, low drive material

· High frequency, fast response time

· High sensitivity for active or passive use

· Ability to use with low voltage or high voltage drive circuits

· Good mechanical and acoustic coupling

· Wide variety of shapes and sizes that can be customized to meet specific requirements and applications

· Wide variety of compositions that can be selected to meet specific requirements and applications

· Quality of each PZT component is ensured by a rigorous testing regimen. Characteristics such as frequency, capacitance, dissipation, coupling, d33 and mechanical properties are measured and verified against our / customer provided specifications.

 


Underwater Communications Applications:


Underwater acoustic modems consist of three main components: 1. the analog front end consisting of an underwater transducer and matching pre-amp and amplifier for acoustic communication, 2. a hardware platform (microcontroller, digital signal processor (DSP), or field programmable gate array (FPGA)) for control and signal processing, and 3. interfaces to oceanographic sensors.While this does not make for an ideal transducer, it is capable of meeting all design specifications by carefully customizing the analog and digital modem design. This custom transducer functions effectively in a few kHz band around 35 kHz and can safely transmit at least 50 W of power in an omni-directional manner. Preliminary functional testing has shown that it is easily capable of transmitting and receiving data across Mission Bay (350 meters).
