Researchers from City University of Hong Kong and Texas A&M University have developed a wearable piezoelectric sensor that notifies the wearer if he or she has been sitting at their desk for too long.

The wearable sensor, which is a series of origami-like folded wires, is worn on the neck while the user is at their desk, monitoring their neck movements as they work. As the wearer moves, the sensor reportedly sends a charge to a connected microcontroller that displays those movements on a computer.

According to the researchers, the material can be used to convert stress to voltage, then measures joint motion according to that. In the event that the wearer moves less than 10 minutes an hour, the sensor will notify the wearer by issuing an alert.

The piezoelectric sensor reportedly has an estimated accuracy around 95% and is detailed in the journal Science Advances.
