SYSTEM FOR ANALYSING PERFORMANCE IN THE USE OF A GLIDEBOARD

The invention relates to a system for analyzing (200) the performance of use of a gliding board (25) comprising: - a database (202) storing reference performances (Tref, Pref); - a sensor (100) sensitive to deformations of said gliding board; and - a supervision unit (204) comprising: - means for determining use performances (Ts, Ps) as a function of measurements (M, T) from said sensor (100); and - means for comparing said use performances with said reference performances; said sensor being secured to said gliding board and comprising: - at least one piezoelectric element secured to said gliding board and configured to generate electrical energy during deformations of said gliding board; and - an electronic processing circuit, powered exclusively by said electrical energy generated by said at least one piezoelectric element.
