Research On PVDF Piezoelectric Film Sensor For Electronic Whiteboard

Electronic whiteboard is the modern equipment which will replace the traditional blackboard and chalk. It is the renovation of the old teachering and meeting mode. Which embodies digital processing, multimedia, long-distance education, netmeeting and overcomes disadvantage of the traditional means, electronic whiteboard is perfect choice of the Computer Aided Education. Nowadays, blackboard is still main tools of teaching in primary schools, middle schools, and colleges. But the dust which the chalk carries may affect teachers and students'health. The general whiteboard solves the problem, but same to the blackboard, it can not capture and save pictures and words on the board. As the electronic whiteboard appears, this sort of whiteboard solve the problem capturing and saving handwriting on board, in this way, students attending class and people who take part in conference do not needed to note anything strenuosity, thereby, the electronic whiteboard has sufficient application in America and Europe. In our country, the electronic whiteboard has sufficient application in lots of classrooms, auditoriums and hotels in recently years.PVDF piezoelectric film has a wide range using of military and civilian and is a kind of very important new materials, Because it can produce...
