A new multifunctional composite made of carbon fiber-reinforced polymers (CFRP) and piezoelectric materials can use vibrations to self-detect tiny cracks. This material could be used in the aerospace, ...

(A) Schematic comparison of the puncture process with and without axial vibration, including 3 stages: pre-puncture (contact compression), puncture (membrane rupture), and post-puncture (insertion ...

During my earliest days in the sensors industry, at PCB Piezotronics (PCB), I can still remember the excitement of publishing my first technical article. It was a primer on piezoelectric sensing ...

To sense shock, vibration, and/or linear motion, accelerometers are beginning to appear in a broad range of new applications. Common types of accelerometers for these applications�various ...

Designed for measuring sound pressure levels and frequencies in the audible range, the Model 130D22 is a combined ICP (Integrated Circuit Piezoelectric) free-field response pre-polarized array ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
