It consists of tubes that are extendable, bendable, and connectable. One technique made li-ion batteries flexible, bendable, twistable and crunchable using the Miura fold. This employed sliding levers and bendable joints that could be protracted and retracted. These formations are clusters of straight, radiating, fibrous crystals that are both bendable and fragile. These are plumulaceous feathers, meaning that they are soft and bendable. Betty Spaghetty is a bendable rubber doll from the Ohio Art Company. She had auburn hair, a Twist N' Turn waist, and bendable legs. Stripwound metal hoses also include "bendable arms", or "swan necks". Newer releases of the Petite Blythe dolls have "sleepy eyes" and bendable bodies. Even more bendable fibers have been developed. In 1965 Midge with bendable legs was introduced. In 1965, bendable legs were added. In 2004, Epson manufactured the world's first bendable microprocessor called ACT11, an 8-bit asynchronous chip. Nokia and the University of Cambridge demonstrated a bendable cell phone called the Morph.
