This wall clock displays your heartbeat in real time #WearableWednesday

Dezeen spoke with designer Ivor Williams about his Uji clock which displays your heartbeat in real time.

Designer Ivor Williams has created a clock that displays your heartbeat instead of the time (+ interview + movie).

The clock, called Uji, uses a wearable ECG sensor to record the electric activity of the heart. This information is sent wirelessly to the clock, which moves its hands backwards and forwards in time with the pulse.


Williams says the project aims to raise questions about the way wearable devices are increasingly be used to harvest “quantified self” data from individuals.

“Uji uses the same technology as wearable devices to detect the heartbeat but it doesn’t use it in a very quantifiable way,” Williams told Dezeen. “It uses it in a very abstract way.”

Williams created the clock with Fabrica researchers interaction designer Jonathan Chomko and product designer Federico Floriani.

The clock is made from a single piece of handmade ceramic features two thin, black hands positioned at midnight. Instead of telling the time, the hands flicker backwards and forwards.

The “quantified self” movement, which began in California in 2007, focuses on finding ways to use technology to collect biometric data, such as measuring blood oxygen levels or tracking insulin or cortisol levels, with the aim of medical self-advancement.

“It’s like the holy grail of technology, this wearable technology with this quantified self. It’s like data driven enlightenment, the idea that you can know yourself,” said Williams. “If we can measure all our vital signs, what’s the value in that?”

He added: “One of the nice things about the clock is that is doesn’t quantify, it doesn’t hold,” Williams explained. “It doesn’t give you any information about whether you have a healthy or an unhealthy heartbeat. It’s not the answer but it’s one way of looking at how technology can be used to do something else.”

Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @
