There are plenty of posture correcting wearables on the market. This robot from Gazelab, a Korean startup, takes the idea to the next level. The Posturebot is a robotic system consisting of a standing desk, an app, a pressure-sensitive mat, and a small robot that mimics your movements.
The Giiro Mat has 600 sensors with 1,024 levels of pressure. You simply have to stand on it to have the Giiro Posturebot monitor your posture. The robot is Alexa enabled.
