Doppel is performance-enhancing wearable tech that can naturally make you feel more alert or relaxed on demand using the innate human response to rhythm. The device applies a small “heart beat” to the inside of the wearer’s wrist to create a subtle yet powerful effect similar to upbeat music that gets you going or downbeat music that chills you out! No monitoring or annoying alerts – just tangible benefits to get your day started with focus or for when you’re winding down. Designers: Nell Bennett, Andreas Bilicki, Fotini Markopoulou & Jack Hooper
