Wearable technologies are the height of fashion
They were among the early innovations to emerge at the world's biggest technology trade event, The Consumer Electronics Show (CES) in Las Vegas. The annual conference will host 150,000 people, all hoping to find the next big thing in technology as we enter 2014.
It also showed off a host of new touchscreen devices and television systems from manufacturers such as Panasonic, Sony, Samsung and LG.
A French company launched what is claimed to be the world's first web-connected toothbrush, the Kolibree. Using an array of sensors, the device analyses the method and duration of a tooth-brushing session, sending back information to an accompanying smartphone app.
"It tells you whether you brushed long enough and reached the hard-to-reach but important parts of your teeth and gums," said a company representative.
The device, which is expected to go on sale later this year for around €80, aims to teach people how to improve their dental hygiene.
"Wearable technology", tipped to be one of the big themes in consumer technology this year, was also out in force at the conference.
A British firm, Fitbug, showcased a selection of sensor-connected bracelets that track and analyse walking, jogging and running speeds.
Another firm, Zensorium, revealed a small, wireless, health-monitoring device called the Tinke. The gadget claims to track a person's heart rate and blood oxygen level, while relaying that information via a smartphone app.
The wearable technology boom even saw the launch of a pair of web-connected socks.
Heapsylon, which designs clothes that connect to online devices, has created a pair of socks, which "enhance" a runner's ability to analyse exercise data.
"Every time you walk, run and exercise, you are generating valuable data that, if properly analysed, can produce meaningful views of your activity and the way you use your whole body," said the company.
Other launches at the show will include curved smart-phones, 105-inch televisions and an array of tablet PCs priced at around €50.
The only major absentee from CES is Apple, which does not showcase new products outside its own conferences.
