Graphene-on-paper sound source devices
WebApr 28, 2024 · Therefore, graphene has a great potential as a next-generation sound source. Photoacoustic (PA) imaging can also be applied to the diagnosis and treatment of diseases using the photothermo-acoustic (PTA) effect. Therefore, in this review, we will introduce the history of TA devices. WebJul 1, 2024 · Graphene is also a nearly ideal thermoacoustic material. The HCPUA for free standing graphene is about 5.8 × 10 −4 J/m∗K, which is one order of magnitude lower than that for single layer CNT film [10]. This gives graphene based thermophones the potential advantage of high acoustic output with low driver voltage [9].
