![]() The acoustic sensor was fabricated with a sandwich structure consisting of 150 nm thick amorphous indium tin oxide on both sides of a 110μ m commercial polyvinylidene fluoride film. In this study, a wearable transparent ultrasonic transducer was developed and applied in a PAI system with excellent performance. However, current systems are overly complex or use bulky piezoelectric materials, necessitating options other than these methods for future PAI systems. ![]() In summary, the study has demonstrated the sensor's potential for large-field PAI application in wearable health devices at a low cost.Ībstract = "Photoacoustic imaging (PAI) has become a popular technique for biomedical diagnosis. Modified imaging phantoms were made to evaluate the lateral resolution, imaging depth, ability to make a convex photoacoustic image, quality of 3D imaging, and capability to perform PAI directly in the ambient environment with a customized phantom. ![]() This single-element sensor exhibited the performance of a 6.7 MHz center frequency, an 86.3%-3 dB fractional bandwidth, and a 20×20 × 36 mm3 volumetric imaging field. Photoacoustic imaging (PAI) has become a popular technique for biomedical diagnosis.
