Seeking PVDF vibration sensor

Seeking PVDF vibration sensor

Seeking PVDF vibration sensor

We are currently developing an acoustic lung imaging system and are looking for a light and very sensitive vibration sensor that could be used to pick up transmitted acoustic vibrations on the human chest. I am wondering if there are any PVDF devices that would be suitable. The device should ideally be a very light disk of 0.16 to 1.5 in^2 (1 to 10 cm^2) and have some sort of shielding against environmental noise. I've heard of the "Atochem SDT1-028" but I'm unable to find it anywhere. I am grateful for any tip. (You can also email to apohlmann@ieee.org) Andreas Pohlmann MIRL Oxford

RE: Seeking PVDF vibration sensor

This sounds interesting- could you tell me what PVDF stands for?

RE: Seeking PVDF vibration sensor

PVDF stands for Polyvinylidene Fluoride.  It is a piezoelectric plastic, also commonly known as Kynar.

RE: Seeking PVDF vibration sensor

I found the SDT1-028, it is now being sold by Measurement Specialities Inc. (http://www.measspec.com) for a rediculously cheap $25. I'm still curious if there are any other transducers. Please drop me a line if you know of any. Cheers

White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
