Conductive‐yarn‐based embroidered devices, with the advantages of being soft, deformable, breathable, and protective for the skin, play an important role in replacing many metallic counterparts. However, embroidered devices face many new challenges in their design methodology and fabrication processes, such as high resistivity and low Q value of the conductive yarns, as well as deformation of device geometries during wearing. Herein, a strain‐free, deformation‐resilient embroidery process for near field communication (NFC) coil antennas is introduced. Coil geometry can endure extreme deformation by stretching with up to 50% elongation, bending with curvature as small as 16 mm in radius, and can still maintain a relatively small variation in its inductance, resonant frequency, Q value, as well as its energy‐harvesting capabilities. The embroidered coil antenna is used in an NFC‐based battery‐free body sensor system. Experiments demonstrate that the system can maintain a stable performance (voltage supply, temperature sensing, and reading range) under various deformation conditions.","PeriodicalId":7187,"journal":{"name":"Advanced Intelligent Systems","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74148506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vigorous research in the past three decades has enriched neuromorphic systems for realizing this ambitious goal. Reverse engineering the brain essentially implies the inference and learning capabilities of a standalone neuromorphic system—particularly, the latter is referred to as embedded learning. The reconfigurability of a neuromorphic system is also pursued to make the system field‐programmable. Bearing these desired attributes in mind, recent progress in digital neuromorphic hardware is overviewed, with an emphasis on real‐time inference and adaptation. Real‐time adaptation, that is, learning in realtime, highlights the feat of spiking neural networks with inherent rich dynamics, which allows the networks to learn from environments embodying an enormous amount of data. The realization of real‐time adaptation imposes severe constraints on digital neuromorphic hardware design. Herein, the constraints and recent attempts to cope with the challenges arising from the constraints are addressed.","PeriodicalId":7187,"journal":{"name":"Advanced Intelligent Systems","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77620474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To realize liquid transportation in these TMAs, LCPs should have excellent photodeformation property and suitable mechanical properties. Herein, linear liquid crystal polymers (LLCPs) with different mesogen orientations are used to prepare TMAs to study their liquid transportation behaviors. The mesogen orientation in each LLCP is formed spontaneously and varies with the spacer length, leading to different deformations of LLCP films. It is found that only LLCPs with mesogens oriented out‐of‐plane realize self‐support of the TMAs, whereas the TMAs with mesogens oriented in‐plane are so weak that they collapse in the radial direction, indicating the importance of mesogen orientation in fabricating three‐dimensional structures. Upon attenuated 470 nm light irradiation, the TMAs deform to an asymmetric conical structure, leading to the motion of liquid slug toward the narrow side. The liquid motion is accelerated in the TMA with longer spacer, showing the control of liquid speed by the mesogen orientation. These photocontrolled TMAs are expected to be applied in biological applications, such as whole blood analysis and flow cytometry, for precise liquid manipulation.","PeriodicalId":7187,"journal":{"name":"Advanced Intelligent Systems","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85774666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, periodically stacked dielectric layers are used in multiple band optical filters. However, the use of dielectrics inevitably results in rigidity and inflexibility, which is not suitable for advanced smart optical sensors fabricated on flexible substrates. Therefore, herein, a strategy to implement soft/tunable multiband optical filters made from silicon nanowire array‐based stackable optical filters (Si NW‐SOFs) composed of polymeric membranes containing vertical silicon nanowire arrays that filter light from visible to near‐infrared regions with a narrow bandwidth is proposed. Theoretical and experimental results indicate wavelength selectivity by geometrical parameters (e.g., diameter, period, and height) and the absence of optical disturbance between the layers in the integrated states. Therefore, multiband optical filters with single‐ to triple‐band stops are easily created by changing Si NW‐SOFs. Finally, imaging demonstrations that involve the filtering of monochromatic light sources of three wavelengths (i.e., red, green, and blue) and fluorescent biological tissues show the practical multiple band characteristics of Si NW‐SOFs.","PeriodicalId":7187,"journal":{"name":"Advanced Intelligent Systems","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81559812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is challenging to form multistable morphing structures under the same condition. Herein, the programmed deformations of a composite hydrogel into multistable configurations under the same condition are demonstrated. The hydrogel consists of integrated units of through‐thickness and/or in‐plane gradient structures, where the former leads to bending, folding, or twisting with a predetermined direction and the latter buckles upward or downward with equal possibility. The bistability of buckling affords the integrated hydrogel with multiple possible configurations. The composite hydrogel with multiple in‐plane gradient units (number: n) and through‐thickness gradient ones (number: m) theoretically has 2n × 1m = 2n configurations under the same condition. Although the integration of units with through‐thickness gradient does not contribute to the diversity of configurations, it favors forming complex and designable configurations. Both experimental and simulation results show that various stable configurations can be obtained in one composite hydrogel under the same condition by controlling the buckling direction of each unit by a selective preswelling step. This concept and strategy are applicable for other intelligent materials and merit their applications in diverse areas.","PeriodicalId":7187,"journal":{"name":"Advanced Intelligent Systems","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75541255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
