Polymer-based piezoelectric ultrasound transducer arrays on glass demonstrating mid-air applications


Christopher Chare, Pieter Gijsenbergh, et. al.

  • The acoustic field of an ultrasound transducer array was measured using XARION's technology in order to characterize the performance of the array
  • With a measured acoustic focal pressure of 300 Pa (144 dB rel. 20µPa) at 256 kHz, 10 mm above the surface, IMEC opens up the possibility of future mid-air haptic feedback applications for large-area thin-film displays
