Numerous wearable devices have been applied in people's daily lives. As the core component of wearable devices, flexible pressure sensors play an especially important role in various fields because of their excellent adaptability to the environment. Various high‐performance flexible pressure sensors have been developed, and much research is still being conducted to increase the performance of flexible pressure sensors. A variety of materials with excellent properties have been created, many advanced manufacturing methods have been developed, and different microstructures have been attempted and applied to flexible pressure sensors. To optimize the performance of sensors, flexible pressure sensors with bionic microstructures from the perspective of bionics have attracted increasing attention, which can bring new designs and improve the performance. This paper mainly summarizes various kinds of flexible pressure sensors with bionic structures developed in recent years. The main contents include the following parts: an introduction to the current state‐of‐the‐art flexible pressure sensors; substrate and active materials, sensing mechanisms, key parameters, and sensitivity optimization strategies; various kinds of bionic microstructures applied to flexible pressure sensors and characterization of the performance; applications of flexible pressure sensors; and prospects and potential challenges of flexible pressure sensors.

Background and aims Asparagaceae subfamily Nolinoideae is an economically important plant group, however, the deep relationships and evolutionary history of the lineage remains poorly understood. Based on a large data set including 37 newly sequenced samples and publicly available plastomes, this study aims to better resolve the inter-tribal relationships of Nolinoideae, and to rigorously examine the tribe level monophyly of Convallarieae, Ophiopogoneae, and Polygonateae. Methods Maximum likelihood (ML) and Bayesian inference (BI) methods were employed to infer phylogenetic relationships of Nolinoideae at the genus level and above. The diversification history of Nolinoideae was explored using molecular dating. Key results Both ML and BI analyses identically recovered five clades within Nolinoideae, respectively corresponding to Dracaeneae + Rusceae, Polygonateae + Theropogon, Ophiopogoneae, Nolineae, and Convallarieae excluding Theropogon, and most deep nodes were well supported. As Theropogon was embedded in Polygonateae, the plastome phylogeny failed to resolve Convallarieae and Polygonateae as reciprocally monophyletic. Divergence time estimation showed that the origins of most Nolinoideae genera were dated to the Miocene and Pliocene. The youthfulness of Nolinoideae genera is well-represented in the three herbaceous tribes (Convallarieae, Ophiopogoneae, and Polygonateae) chiefly distributed in the temperate areas of the Northern Hemisphere, as the median stem ages of all the 14 genera currently belonging to them were estimated less than 12.37 Ma. Conclusions This study recovered a robust backbone phylogeny, providing new insights for better understanding the evolution and classification of Nolinoideae. Compared with the deep relationships recovered by a previous study based on transcriptomic data, our data suggest that ancient hybridization or incomplete lineage sorting may have occurred in the early diversification of Nolinoideae. Our findings will provide important reference for further study of the evolutionary complexity of Nolinoideae using nuclear genomic data. The recent origin of these herbaceous genera currently belonging to Convallarieae, Ophiopogoneae, and Polygonateae provides new evidence to support the hypothesis that the global expansion of temperate habitats caused by the climate cooling over the past 15 Ma may have dramatically driven lineage diversification and speciation in the Northern Hemisphere temperate flora.
