N2 - In this research, an attachable transparent ultrasonic transducer is developed with 86.3% -3dB fractional bandwidth, 6.7MHz center frequency, and 20×20×36mm3 volumetric imaging window which shows the excellent photoacoustic (PA) imaging performance. This transparent transducer is fabricated by depositing 150nm thick Indium tin oxide (ITO) via sputter system on both side of a 110um commercial Polyvinylidene fluoride (PVDF) film in room temperature. Bionic imaging phantoms are made by 3D printer to evaluate the capability of perform PA imaging with skin-like surface, imaging depth, and quality of 3D imaging. A 532nm Nd:YAG laser with 5ns pulse width is penetrated through the ultrasound transducer and excited PA signals when encountered imaging targets. In summary, the competence of achieving in vivo P A blood vessel imaging for wearable healthcare monitoring system using this sensor has been demonstrated.
