Temporal–Spatial Replication of the Pulse Haptic Sensation Empowered by Multifunctional Piezoelectret

Compared to the Western medicine diagnostic techniques, the Traditional Chinese Medicine (TCM) pulse diagnosis has unparalleled safety, instantaneity and environmental friendliness. Although the effectiveness of the pulse diagnosis has been verified by thousands of years of clinical practice, it still faces skepticism due to its obscure diagnostic process and strong subjective characteristics. In this work, feasible solutions for the modern and future oriented development of the TCM pulse diagnosis through the combination of innovative multifunctional piezoelectret devices and advanced algorithm model have been explored. Dynamic sensing, static sensing, and haptic feedback are realized simultaneously by the uniquely designed piezoelectret structures with similar small thin sheet appearances, combined with a customized pressure device to simulate the three‐fingerpulse diagnosis process. On this basis, three application scenarios, including the automated pulse diagnosis process, temporal and spatial replication of the pulse haptic sensation, have been demonstrated. The complete set of solutions from the cooperation of engineering and medicine greatly expand the TCM concepts and enrich the application scenarios.
