Tilly Lockey

Tilly Lockey is a British amputee known for her bionic arms developed by Open Bionics, which she has used since 2016.

Lockey contracted meningococcal septicaemia as a baby in 2007, at the age of 15-months. Despite her parents being told that she was likely to die, Lockey survived following a successful operation to have both arms and her toes amputated.

Lockey was initially provided with simple prosthetics from the NHS. While researching 3D printing, Lockey's mother discovered Open Bionics, who were looking for a below-the-elbow amputee to trial new prosthetic arms. Since being chosen in 2016, Lockey has used bionic arms developed by the company, which enable her to perform actions such as picking up small objects and playing video games. These arms are the first of their kind to be medically-approved in Britain.

In 2014, Lockey's custom-made bicycle was stolen; it was recovered four days later and two people were charged.

One set of her arms were based on the Deus Ex video game. In 2019, Lockey received new custom arms designed by the team creating Alita: Battle Angel.

Lockey now creates and shares make-up tutorials online. She featured in the video for Kate Nash's 2019 song Bad Lieutenant.
