A sensor arrangement for monitoring physical activity associated with a living being, comprising a flexible board (70) to which is fitted a transducer (80) for converting a distortion of the board into an electrical signal. The board comprises discontinuities (94) which enable parts of the board to distort somewhat independently of other parts of the board. The living being lies or sits on a cushion or mattress (30) under which is located the board. The signal from the transducer (80) is passed onto circuitry (50) which can detect the presence of the physical activity, which may be heartbeat, breathing or limb movement. The discontinuities can be plurality of slots formed in the board, a plurality of grooves formed in the board or a plurality of ribs formed in the board.

L'invention concerne un dispositif de détection pour contrôler une activité physique associée à un être vivant. Le dispositif comprend un panneau souple (70) auquel est fixé un transducteur (80) qui convertit une distorsion du panneau en signal électrique. Le panneau comprend des discontinuités (94) qui permettent une déformation de certaines parties du panneau, cela, de manière passablement indépendante des autres parties du panneau. L'être humain s'allonge ou s'assied sur un coussin ou un matelas (30) sous lequel se trouve le panneau. Le signal émis par le transducteur (80) est transmis au circuit (50) qui peut détecter la manifestation de l'activité physique (pulsations cardiaques, respiration ou mouvement d'un membre, par exemple). Les discontinuités peuvent être constituées de plusieurs fentes de plusieurs sillons ou de plusieurs nervures formés dans le panneau.
