Bejewelled bionics

Wearable technology was out in force this month at a dedicated show in London - here are some of the most interesting items on display.

Open Bionics is a project to create a prosthetic arm with a robotic hand for under £1,000 - far less than the tens of thousands of pounds such limbs usually cost.

The crowd-funded project has produced a number of 3D-printed prototypes, which detect electromyographical signals - electrical pulses sent to muscles in the arm - allowing the user to control the hand.

Joel Gibbard, the Bristol-based roboticist behind the project, and his team are working on refining the capabilities and design of the arm and securing approval for its use by medical organisations.

Each arm can be shaped and designed to suit the needs of the user, as seen here with this dazzling prosthetic studded with Swarovksi crystals, made for YouTube star and actress Grace Mandeville.
