After Manufacturing 1: Connecting to PZT Components
In this months article we will be starting our "After Manufacturing" series of newsletters. These newsletters will focus primarily on "what to do?" with the piezo ceramics starting with this issue, connecting to piezo. Throughout the series we will be continuing with a logical progression or uses and design information

Transmitting Acoustic Signals Through Water: Echo Sounding
There are many industries that need to “see” underwater. For example, companies that rely on sea transportation need to know how deep water is to ensure a ship does not run aground. Fishing operations need to find fish, and researchers hunt for shipwrecks.
Not only do they need to have reliable

Ceramic Manufacturing Series – Testing and Packing PZT Ceramics
In this month's article we will be discussing some of the most common electrical and physical properties specified by customers when purchasing PZT ceramics for a specific application, how to test for these often specified properties, and some general equipment choices.
Common Properties
Generally speaking, when ordering a PZT ceramic for a

Ceramic Manufacturing Series – Poling PZT Ceramics
To understand the poling process, a basic review of the crystal structure is helpful.
Piezo Crystal Structure:
Typical PZT materials exhibit a perovskite structure. One can visualize this structure as a cube with eight large lead (Pb) ions at the corners of the cube. Six oxygen (O) ions are situated one inRead More...
Ceramic Manufacturing Series – Electroding PZT Ceramics
This month we will be covering electrodes and electrode firing for PZT ceramics. We will primarily be discussing fired-on silver electrodes, but will touch on several other techniques commonly used in the industry.
Electrode Considerations:
When determining which electrode system is right for your application it is important to consider the endRead More...
Ceramic Manufacturing Series – Machining PZT Ceramics
If you have been following our manufacturing series of articles, then you know we have fired ceramic and are about to discuss shaping and machining. If you haven't been following, you should be!
When determining how to machine a ceramic component, it is important to remember that the finished electrical properties

History of the Development of Ultrasound Technology
The science of sound is an ever-evolving and vast study. It is documented as far back as the sixth century BC when Greek philosopher and mathematician Pythagoras constructed mathematical properties of stringed instruments. Sound waves, whether heard audibly or at such a high frequency that they cannot be heard by
