The invention discloses a flexible piezoelectric cilia
sensor array for detecting flow velocity, flow direction and air pressure, which belongs to the field of bionic
airflow sensing and comprises an air bag cilia
sensor array, a piezoelectric film
sensor array, a
signal processing module, an
airflow signal output end, a comprehensive
signal output end and a wire. The air bag
cilium sensor array is composed of air flow sensing units and comprises a base, a supporting piece, a film air bag, an annular
electrode and piezoelectric cilia. The piezoelectric film sensor array comprises a common
ground layer, a sensing layer, a positive
electrode layer and an isolation
protection layer from top to bottom; and the
signal processing module comprises a comprehensive signal receiving end, an
airflow signal receiving end and an external equipment connecting end. The air bag
cilium sensor array and the piezoelectric film sensor array sense air flow and air pressure signals in real time and input the signals into the
signal processing module, electric signals output by the connecting end of external equipment are analyzed, and multi-dimensional, real-time and high-sensitivity detection of the flow speed, the flow direction and the air pressure is achieved.
