Fig. 1: Overview of the disposable snCMUT patches.
From: Silicon nanocolumn-based disposable and flexible ultrasound patches
a Schematic illustrations of disposable snCMUT patches for continuous monitoring of both sides of the human carotid arteries. The disposable snCMUT patches are lead-free and avoid environmental restrictions. b Schematic illustrations of single snCMUT patch including PDMS lens, snCMUT array, and in-house designed FPCB. c Schematic illustrations of 4-cells of snCMUT and driving mechanism of substrate-embedded silicon nanocolumns as springs. Optical images of the mechanical compliance of the snCMUT array when bent with a tweezer (d) and the disposable snCMUT patch when twisted (e). f B-mode imaging of the common carotid artery (CCA), jugular vein (JV), and sternocleidomastoid muscle (SCM) while the subject is rested (left). M-mode imaging of the pulsation pattern of CCA walls (right).
