Nanotechnology enables materials and components that are flexible, stretchable, transparent and remarkably strong. Fibril proteins are woven into a three dimensional mesh that reinforces thin elastic structures. Using the same principle behind spider silk, this elasticity enables the device to literally change shapes and configure itself to adapt to the task at hand.

A folded design would fit easily in a pocket and could lend itself ergonomically to being used as a traditional handset. An unfolded larger design could display more detailed information, and incorporate input devices such as keyboards and touch pads. 

Even integrated electronics, from interconnects to sensors, could share these flexible properties. Further, utilization of biodegradable materials might make production and recycling of devices easier and ecologically friendly.

Furthermore an engineer from the University of Warwick, has been working with plastics manufacturers to come up with a phone cover made of biodegradable plastic - an alternative to the usual plastics that can last hundreds of years in a landfill When buried, the biodegradable plastics break down into natural minerals. The microorganisms in the soil break down the plastic and provide nutrients for plants.
