Cameroonian inventor Arthur Zang has won a £25,000 $37,000 prize for his device that does heart examinations.

It allows health workers to give heart examinations and send the results to heart specialists far away.

BBC Africa's Mamadou Moussa Ba says there are just 50 cardiologists in Cameroon, which has a population of 20 million people.

The results from his Cardiopad are sent to a cardiologist via a mobile network and can be interpreted within 20 minutes.

"My uncle died from a stroke after I had already started working on the Cardiopad and this gave me extra motivation to see the project through to the end", Mr Zang told the BBC earlier this month.

Last year's winner of the award was Tanzanian chemical engineer Askwar Hilonga who invented a sand-based water filter that absorbs anything from copper and fluoride to bacteria.
