“…Simultaneous US/PA imaging allows visual observation of arterial pulsation and movement of non-arterial blood vessels, providing us clear evidence. With the recently developed transparent US transducers, such multimodal sensing and imaging may be easily implemented [37] , [38] . In addition, the PAM-PPG system has the potentials to provide blood oxygen saturation in different sites through multispectral analysis, and each modality has been separately proved for this purpose [39] , [40] , [41] , [42] , [43] , [44] .…”

The microvascular networks regulate blood flow to biological tissue and are the primary site for the exchange of hormones, gasses, nutrients, water, and waste between blood and interstitial fluid. 1,2 Microvessels, i.e., arterioles, venules, and capillaries, form the microvascular networks. 1 The walls of arterioles mainly comprise a layer of endothelium and smooth muscles to allow for the flow of blood into capillaries through vasoconstriction and vasodilation, which are regulated by tissue oxygen concentration, autonomic nervous system, and hormones. 1 Capillaries, the smallest blood vessels, receive blood from arterioles; and they have a single cell thick layer of the endothelium to facilitate the exchange of nutrients and gasses between blood and interstitial fluid. 1 Capillaries terminate into venules whose walls contain fibrous tissue, which allow them to primarily act as volume reservoirs. 1 Any loss in blood flow, changes in oxygen concentration, dysregulation in the autonomic nervous system, etc. due to various pathologies, such as diabetes, sickle cell anemia, hypertension, bodily injury, and tumor growth, cause disruptions in microcirculation and, in severe cases, lead to irreparable harm and

“…Emerging applications such as micro-mirror for LIDAR, haptics for humanmachine interfaces, micro-pumps, as well as PMUT for fingerprint, medical probe or gesture recognition are also based on thin film PZT actuators [3]. In recent years, transparent piezoelectric thin films are showing growing interest for transducers and actuator functions in application domains like photoacoustic imaging [4][5][6], haptics [7,8] and acoustics [9].…”
