According to the latest announcement by the Kansai University, the first piezoelectric fabrics has been manufactured by their research team. Prof. Yoshiro Tajistu, faculty of engineering science at the University has developed this fabric for wearable devices using polylactic acid fiber and carbon fiber. Earlier, the Kansai University manufactured a flexible, transparent piezoelectric film with alternate lamination of PLLA and PDLA. The piezoelectric fabric is the newest application of this technology. As this fabric bear the ability of generating an electric charge in response to mechanical stress and vice versa, it will be effective for both, actuators and sensors. The interesting part of this invention is that twilled and satin weave version of the fabric has also been produced apart from the plain one for different applications. Plain, satin and twill weave detects bending, twisting and three dimensional motion, respectively. Moreover, the twilled version also detects shear, bending and twisting.

This piezoelectric fabric will be applied for elaboration of monitoring human actions simply through clothing they wear. This kind of application works by contributing to the evolution of lots of things in the field of surgery, elderly care, space exploration and so on.
