Invisible locks and glasses for hay fever sufferers were among 1,000 creations on show Friday at Geneva’s annual inventions fair.
For the next 10 days, some 600 exhibitors from 44 countries will try to attract customers and marketing partners for ideas ranging from industrial gear to quirky gadgets for the home.
A key theme was security.
A French exhibitor offered a supposedly unpickable “invisible lock” operated remotely by an electronically linked key. A cordless phone from Belgium doubled as a remote control device for a home security system. And an electronic pen from Peru was said to be reliable in spotting forged signatures.
Health also was a prime concern of inventors.
A British company displayed sunglasses for hay fever sufferers. They are designed, it said, to prevent pollen granules from entering the eyes by pumping filtered air through holes in the frames.
