Radio-Frequency (RF) communications are increasingly subject to high interferences caused by ubiquitous wireless devices. Ultrasonic communication can serve as an alternative wireless communication mechanism to compliment RF communications. However, traditional ultrasonic transducers have extremely narrow bandwidth that prevents them from being deployed in real-world applications. In this demo, we demonstrate the implementation of an ultrasonic communication system using graphene-based electrostatic acoustic transducers. Our experimental results show that the prototype system works on 100 kHz ultrasonic carrier, and can achieve data rate up to 20 kbit/s with bit error rate lower than 10(-5) at a transmission distance of 25 cm and transmission power of 2 mW, significantly faster than the state-of-the-art ultrasonic communication approaches(1). |
