Arthur Zang never leaves his workshop for several days. The days of this young computer engineer, inventor of Cardiopad (a touch-pad for medical purposes), have become long and exhausting.

This because he began assembling these devices that will soon be marketed. In the premises of his company, Himoremedical in Yaounde, three young engineers are busy at his side to assemble the shelves.

The goal is to produce 30 per day. If this course is well maintained, Arthur Zang hopes to complete the making of the first 300 Cardiopads in the next two weeks.

"We work all day”, said the engineer with eyes covered with dark circles while his working day is far from over. "I have set up a team of three technicians who are training engineers and one that has a BTS in electronics."
