Tokyo, Japan (CNN)Located in the industrial city of Chiba, just outside of Tokyo, CEATEC is the biggest electronics show in Japan.
Each year, the nation which gave the world the bullet train, the Walkman and blue LED light showcases its latest, cutting-edge consumer technologies.
In 2017, Sharp introduced the 8K era with its dazzling 27-inch monitor of the same resolution due to release next month, Lenovo debuted a Star Wars Jedi Challenge game that allowed users to engage in virtual reality lightsaber battles and there were robots galore. This is, after all, Japan.
CNN highlights eight of the quirkiest inventions showcased at the event.
Get the perfect chew
It looks like a Bluetooth hands-free device, but bitescan is actually measuring your chewing strokes as you eat.
Hung from the ear, it is smaller and lighter than existing bite counters (they're normally attached to the chin) and can determine a user's bite speed, number of bites per minute and type of bite using a waveform detected on the back of the ear.
Sharp has somewhat gamified the concept: the device syncs up to a smartphone app which categorizes results by animal type i.e. slow chewers are tortoises.
The product will go on sale next year. Sharp says it will then share the data it collects with Japanese universities. The aim, it says, is to allow the user to achieve the perfect chewing habits.
Quite why we need to do this will presumably become clearer in time.
