Several innovative healthcare products were recognized at the Consumer Electronics Show. A standout winner is Able Planet's just-launched Personal Sound amp, the "first ever" near-ear canal personal sound amplifier. This nearly invisible device was designed to improve sound quality in noisy environments. Another hearing device earning accolades is the AMP from Starkey. This tiny hearing aid fits into an ear canal, so it is essentially hidden from view. Another winner: the Rydis H1004-II robot from Moneaul. While rolling around, this futuristic-looking device can play therapeutic music and allow Internet access — all while purifying the air.
