The winners of the 2016 Tech4Good awards have been announced at a ceremony at BT Centre.

Now in its sixth year, the awards celebrate technological innovation that makes the world a better place.

Organised by national charity AbilityNet and supported by BT, prizes were awarded in a range of categories and an overall Winner of Winners was crowned.

Kate Russell, author and award-winning blogger, hosted the awards and was impressed by the entries.

"There are a lot of big problems in this world and as well as some really interesting solutions to those, it’s fascinating to me how some of the smaller world problems that are important to this year’s winners are being tackled through technology innovations,” she said.

The 2016 Winner of Winners was nine-year-old Arnav Sharma (below) who also won the Tech4Good People’s Award with the AsthmaPi Kit, which uses a Raspberry Pi computer to help parents of asthma sufferers.
