An elastic bandage is a "stretchable bandage used to create localized pressure". The CNT thin film loudspeaker is transparent, stretchable and flexible. They develop the first stretchable nylon/elastane (glove) with leather coverings. The ghost's extending arm was made from stretchable plastic tubing covered in fabric. The membrane is at least 5 micrometres thick, translucent, and stretchable with good stretch recovery. They are usually made from a material that is itself soft and stretchable. Ionic gels can also serve as elements of high-performance, stretchable graphene transistors. Gleek has a stretchable, prehensile tail which can be quite useful. An ideal spring is taken to be massless, frictionless, unbreakable, and infinitely stretchable. These grips are highly stretchable to ensure the grip wraps neatly around the racquet's handle. The technology is based on stretchable semiconductor materials (Elastronic). The foreskin is mobile, fairly stretchable, and acts as a natural lubricant. Applications for stretchable electronics include energy storage devices and solar cells. Because its two threads run straight and parallel, a straight stitch is not natively stretchable. The low prevalence in elderly patients may be due to a less stretchable dura mater.
