CES 2017: The latest health tech on display in Las Vegas

There’s a lot of walking around at CES, the world’s largest annual consumer technology trade show, in Las Vegas. CGTN’s Phil Lavelle unveils some of the gadgets on show.

Kang Res, the founder of Gyenno, has flown all the way to Las Vegas from China, with his spoon for Parkinson’s sufferers.

The product is small but the concept is huge.

A year after his company debuted its first device, Gyenno is back for second helpings. Spoon, v2, has a built-in internet connection, which syncs to the cloud and is a fraction of the size.

Health is a major topic at CES this year – from the skin to sleep to sun exposure.

There are thousands of solutions for an alphabet of ailments, and even some for keeping those ailments in check, providing new solutions to old problems.

Like this smart watch and smart sensor from the French firm, PK Vitality. It tastes the skin and gives a glucose reading. No invasive pins or needles needed.

The Pill Drill helps patients who are prescribed a number of medications to keep on top of their dosage, in an ultra-connected way.

And this company has invented an eye test that can detect autism in babies at 12 months when current diagnoses happen at 4-5 years.

For a lot of the companies, their devices may not catch on. They won’t get the investment. They won’t capture the imagination.

But the spirit here is one of optimism. Many here desperate to make a difference to the lives of millions of others.
