In this paper we present experimental analysis of a coaxial cable with a wrapped piezo-polymeric film as sensing element. In particular we address the mechanical to electrical conversion performance of 10 cm of cable having an external diameter of 2.7 mm. The active material is used as dielectric between the center core and the outer braid. When a mechanical stimulus is applied, a voltage is generated proportional to the applied stress. It is worth noting that the proposed transducer, which can be also used as coaxial cable, presents several intriguing advantages such as soft, flexible and stretchable structure. The measurement method will be presented and a characterization of the output voltage as function of external applied vibrations will be here presented demonstrating the capabilities of the proposed device which can be also useful as artificial skin and transducer for biomedical applications.

Abstract
In this paper we present experimental analysis of a coaxial cable with a wrapped piezo-polymeric film as sensing element. In particular we address the mechanical to electrical conversion performance of 10 cm of cable having an external diameter of 2.7 mm. The active material is used as dielectric between the center core and the outer braid. When a mechanical stimulus is applied, a voltage is generated proportional to the applied stress. It is worth noting that the proposed transducer, which can be also used as coaxial cable, presents several intriguing advantages such as soft, flexible and stretchable structure. The measurement method will be presented and a characterization of the output voltage as function of external applied vibrations will be here presented demonstrating the capabilities of the proposed device which can be also useful as artificial skin and transducer for biomedical applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
