Photoacoustic sensing and imaging techniques
have experienced tremendous research progress, ranging
from fundamental physics and methodologies to various
biomedical and clinical applications in recent years.
However, the state-of-art photoacoustic systems still suffer
from high cost and bulky size, which hinders their
potential applications for low-cost and portable diagnostics.
In this paper, we propose the design for a palm-size
photoacoustic sensor prototype. The design’s lower cost
and smaller size would allow it to be used for portable
photoacoustic sensing applications like oxygen saturation
and temperature. By converting the high-frequency photoacoustic
pulse signal to low-frequency photoacoustic DC
signal through a rectifier circuit, the proposed photoacoustic
receiver could potentially reduce the cost and device
size efficiently, compared with the conventional highspeed
data acquisition card interfaced with computer solutions.
Preliminary testing is demonstrated to show its feasibility
for photoacoustic sensing applications.
