• Transducer design functions as both electrostatic speaker and/or microphone-ultrasonic sensor

• Novel, Patent Pending design

• Developed at Lawrence Berkeley National Laboratory – UC Berkeley

• Graphene diaphragm is thinner, stronger and extremely responsive

• 100% air dampening vastly improves response and energy efficiency

• Proprietary power/signal Integrated Circuit (IC) chip will support transducer

• IC and Software designs will drive new transducer applications
