We have special sensors that can be put inside your floor. It's a layer about 4mm thick that can be placed under a carpet, a layer of wood or even covered by a thin layer of concrete.
The sensors can have any shape you want. our standard sensors form a rectanular grid of 25cm x 25cm. But you could also shape them in a circle, a line or a Piano keyboard.
