Smart cup by Yves Behar knows
precisely what's in your drink

Yves Behar has designed a smart cup called Vessyl, which detects what you're drinking and displays its nutritional contents in real time.

Behar's studio Fuseproject was commissioned by San-Francisco-based scientist Justin Lee to design Vessyl, which has been in development for seven years.

When used with the Vessyl mobile application, the cup can display the levels of fat, calories, sugars and caffeine in any liquid poured inside it.

"Integrating breakthrough technology into everyday products is always a challenge, at the same time, this is exactly how design makes tech products easily adoptable in life," Behar told Dezeen.

"For Vessyl, we made the cup comfortable and familiar and made the display of the information discreet and only visible when needed."

Each cup has a spill-proof lid and non-stick interior, as well as a front-facing screen that displays nutritional information.

Vessyl can be switched on by tilting it, and an accompanying coaster acts as a wireless power source that can provide a week's worth of battery life after a 30-minute charge.

"The faceted exterior surface is just enough of an indicator that something might be different about the cup, and provides it with a porcelain-like surface reflectivity," said Behar.

Behar has led the design on a number of other smart products including an Android-based game console called Ouya and a range of wearable technology for Jawbone. Last week Behar unveiled a design for a device that could create a "connected garden" and automatically water thirsty plants. 

"Every tech product on the body like Jawbone or in the home like August is different," he told Dezeen.

"But there are definitely principles that apply across the board for me such as integration in everyday life and discretion."

The cup also features a built-in hydration detector called Pryme, which uses a vertical bar of light to tell the user how much water they need to consume, once they've entered details including their age, weight and height into the Vessyl app.

"We are frequently unaware of the impact things we put into our bodies can have –  think about all the unlabelled things we drink, like a homemade smoothie, a cappuccino from your local barista or a mixed drink at the bar," said Justin Lee, Vessyl's CEO and co-founder.

"All of these beverages affect our bodies in different ways and Vessyl helps us understand their impact."

  • uhwha?

    I’m all for the unnecessary, but this is extremely unnecessary.

    No! Why?

    Finally! I think I can safely speak for everyone when I say it’s about time someone figured out a way to sync my phone with a cup! It’s 2014 for crying out loud and I’m still relying on my sense of thirst to know when I’m thirsty. No more! No more I say!

    They want everything to be smart now. Soon we will have the smart condom to know how much you ejaculate!

    That would be great Manuel! I’d want it to be able to find the strongest sperm and work out, by referencing live data from the womans’ eggs, what the child it stopped you both having would have looked like. Maybe you could store all your unborn children on an app and have artificial intelligence bring them to life! Then you would be able to carry them around with you all the time, imagine that. You could love and nurture them and watch them grow up and fall in love with other peoples unborn children.


    This is a beautiful piece of industrial design. I’m not a tech-head (no Facebook account even), but as an architect turned distributor of health and nutrition products, I really appreciate this design.

    People, do not consider beverages as food, even though it’s very often their greatest source of sugar and calories (as well as other very nasty stuff). We certainly don’t need a cup to tell us that we’re drinking beer if we just poured beer into it.

    I like this product because it enables us to examine the nutritional content of the beverages we consume. The first thing I’ll pour into this cup (if I can get one) are all “health drinks” and drinks marketed as “healthy”. The second will be a gin & tonic ; )

    I guess if he can’t put a ‘Y’ shape into the design, he’s gonna make damn sure there’s a ‘Y’ in the name!

    • JamesPleaze

      The dumbest smart device out there.

  • Aaron

    Absurd and ridiculous.

  • sirius

    Sky mall. I’m sorry “vessyl”.

  • Ignacio Davola

    Just great! I’d rather call it inVessyl…
