“…Second, the data shown in Figure 7B(ii,iii) suggest that the sensor array can be used to map the position of the radial artery in agreement with anatomical features known from the literature. [ 80 ] Third, the pulse waveforms acquired at different positions of the radial artery (i.e., coordinates (3,a), (2,c), and (2,d)) can be used for personalized pulse diagnosis. For instance, in traditional Chinese medicine (TCM), the practitioner uses three fingers to palpate specific positions of the patient's wrist radial artery (i.e., Cun, Guan, and Chi).…”

Wearable flexible strain sensors with spatial resolution enable the acquisition and analysis of complex actions for noninvasive personalized healthcare applications. To provide secure contact with skin and to avoid environmental pollution after usage, sensors with biocompatibility and biodegradability are highly desirable. Herein, wearable flexible strain sensors composed of crosslinked gold nanoparticle (GNP) thin films as the active conductive layer and transparent biodegradable polyurethane (PU) films as the flexible substrate are developed. The patterned GNP films (micrometer‐ to millimeter‐scale square and rectangle geometry, alphabetic characters, and wave and array patterns) are transferred onto the biodegradable PU film via a facile, clean, rapid and high‐precision contact printing method, without the need of a sacrificial polymer carrier or organic solvents. The GNP‐PU strain sensor with low Young's modulus (≈17.8 MPa) and high stretchability showed good stability and durability (10 000 cycles) as well as degradability (42% weight loss after 17 days at 74 °C in water). The GNP‐PU strain sensor arrays with spatiotemporal strain resolution are applied as wearable eco‐friendly electronics for monitoring subtle physiological signals (e.g., mapping of arterial lines and sensing pulse waveforms) and large‐strain actions (e.g., finger bending).
