Moov chair charges your phone while you fidget, Via Designboom
nathalie teugels presents ‘moov’, a chair that charges your phone or tablet while you sit down on it and move. in order to achieve this, the dutch designer used the piezoelectricity effect which gives certain materials the ability to generate an electric charge in response to applied mechanical stress like pressure or vibration. the sensors placed on the chair are activated as someone takes a seat or when they get back up. this motivates the user to move the whole time, due to the flexible and cantilevered structure of its frame. a battery, where all the electricity is stored so none of it gets lost, is connected to a USB outlet located at the armrest, making sure the phone is never too far away.

nteugels comments on her project that, ‘the whole idea started from a very personal story, one about hyperactivity and ADHD. sit still was something that I heard a lot during my childhood. because of this, I wanted to design something where my energy could get used in a positive way. therefore, I created a chair where I cannot sit still and where moving is a must. this is a chair for people who have the habit of tapping their feet on the ground the whole time, or simply moving on the chair constantly.’
