High-precision neuromodulation with high efficacy poses great importance in neuroscience. Also, ultrasound frequency in sub-MHz gives greater penetration depth of neuromodulation in vivo, and has many different biomedical applications, such as ocular drug delivery, arterial hyperplasia reduction, etc. Here we fabricated a series of carbon-nanotube (CNT) and polydimethylsiloxane (PDMS) mixture films with different CNT concentration and thickness, which can generate highly efficient sub-MHz ultrasound. We discovered that 0.8% CNT concentration CNT/PDMS films gave approximately 1 MHz frequency, below which we achieved tunable frequency in sub-MHz area. Additionally, we adjusted the PDMS base to curing agent ratio and discovered that the 2:1 ratio's optoacoustic conversion efficiency is 1.6 times greater than the typical 10:1 ratio. Our work offers a potential way to increase photoacoustic conversion rate by optimizing CNT/PDMS films' fabrication for further photoacoustic-related applications.
