The film element, screen printed with silver ink, is folded over on itself, providing self-shielding of the transducer area. This is important in applications in high EMI environments. The SDT1 can be adhered to other surfaces using double sided adhesives, epoxy or cyanoacrylate (super glue). Care should be taken if the sensor is to be removed, as the double-side adhesive can peel the metallization from the film. When adhered to a surface in this manner, the SDT1 is an excellent contact microphone or dynamic strain gage. The output from the SDT1 can input directly to an oscilloscope (10 MΩ preferred input impedance) or a signal analyzer.
