Abstract of GB 2456822 (A)
An electronic transducer comprises a
knitted structure extendible in two dimensions defined by its courses and
wales. An electro-conductive yarn 4 defines a single course in the structure
adjacent non-conductive yarns 2, and is part of a circuit providing an
indication of an electrical characteristic of the yarn. The structure may comprise
a plurality of the conductive yarns used individually in series or in parallel.
The structure may be such that extension in the course direction X causes
separation of the loops and extension in the wale direction Y urges loops
together to cause a short and consequential reduction of resistance of the
electro-conductive course. Alternatively the non-conductive yarns may be of low
modulus or elastomeric which are extended during knitting to result in a
structure in which successive loops of the electro-conductive yarn are urged
against one another (Fig 2). The electrical characteristic of the
electro-conductive yarn may be resistance, piezoelectric, capacitive or
inductive.
