Summary:This paper presents a wireless dynamic measurement of the air blast overpressure. This system is based on a piezoelectric PolyVinyliDene Fluoride (PVDF) sensor fully characterized in a shock tube calibration instrument. A dedicated optimized wireless system is used in order to transmit the transient pressure. The pressure signal inside a fire ball was recorded wirelessly for the first time during the open field detonation of an explosive. The proposed simple and low-cost technique allows transmitting high bandwidth pressure signal and could be an alternative to the conventional wired transmission setup.
