Atrial fibrillation (AF) as one of the most common cardiovascular diseases has attracted great attention due to its high disability and mortality rate. Thus, a timely effective recognition method for AF is importance diagnosing preventing it. Herein, we proposed novel intelligent sensing system which combined Traditional Chinese Medicine (TCM), flexible wearable electronic devices, artificial intelligence. Experiment simulation synergistically verified that pressure sensor arrays designed according TCM theory could synchronously obtain 3D pulses at Cun, Guan, Chi. Combined with homemade signal acquisition pulse signals labeled by doctors diseases, differences in between ones without can be picked up clearly. Enabled convolutional neural network (CNN) database, model was formed rate 90%. As proof concept, intelligence-enabled atrial diagnosis been used detect patients hospitals, showing 80% This work provides new strategy precisely diagnose remotely treat AF, well accelerate development Modern treatment.

Abstract Traditional electronic skin (e‐skin), due to the lack of human‐skin‐like complex sensitive structures and their derived autonomous perception decision‐making capabilities tactile nervous system, makes it difficult achieve performance deep‐level intelligence comparable human skin. Herein, a soft/hardware‐synergy‐motivated epidermis‐dermis bionic (EDB) e‐skin is proposed, inspired by interlaced papillary projections between epidermis dermis. Benefiting from interlocked microdome iontronic effect, EDB exhibits maximum sensitivity 1558.3 kPa −1 (<1 kPa), low limit detection <0.01 Pa, fast response/recovery time <5.6 ms. In addition, feasibility hardness/softness‐based material technology verified through test results COMSOL finite element analysis. Further, after being equipped with “tactile system”, that is, hardware functional modules terminal artificial neural networks, an intelligent robotic sensory system integrated fingertips developed. With single touch, this can autonomously in real‐time perceive different materials, achieving abilities those humans.

Abstract A sensor which is able to detect both the high‐ pressure and subtle crucial for applications such as physiological health monitoring human‐machine interactions. However, current sensors often struggle meet these requirements, they usually rely on a single compression mechanism. In this study, microvilli‐microstructures reported capable of tracking ultra‐broad‐range pressures based synchronous‐compression The mechanism includes: i) increase microvilli‐induced electron‐transfer, ii) microstructure contact area, iii) decrease multi‐walled carbon nanotubes spacing. At high‐pressure stages, mechanisms contribute synchronously changes in resistance. Hence, can measure 5 kPa change under extremely (750 kPa) conditions meniscus simulation, where commercial fails.
