Abstract Highly stretchable aerogel films are attractive for advanced next‐generation electronics. However, it is a great challenge to achieve high stretchability films. Here, several types of unprecedented ultra‐stretchable semiconducting polymer‐based with crimpled porous structures developed via crosslinking and template methods combined uniaxial biaxial pre‐stretching strategies. The obtained by exhibit ultrahigh up 100–200%, while those show 50%. resulting strain‐insensitive electrical...
We present a dynamic strain field mapping method based on synchrotron X-ray digital image correlation (XDIC). Synchrotron sources are advantageous for imaging with exceptional spatial and temporal resolutions, speckles can be produced either from surface roughness or internal inhomogeneities. Combining speckled DIC allows one to map fields high resolutions. Based experiments void growth in Al deformation of granular material during Kolsky bar/gas gun loading at the Advanced Photon Source...
Abstract Organic electrochemical transistors (OECTs) possess low operating voltage and excellent amplification capability show promising applications in biosensors flexible electronics. However, the active layers of OECTs are usually dense films, which limited ion penetration/transport, resulting performances OECTs. Here, unprecedented high‐performance multifunctional based on nanoporous (mainly 2–60 nm), high‐specific‐surface‐area (255–281 m 2 g −1 ), conjugated polymer aerogel films...
Abstract This paper presents an adaptive robust motion control algorithm for linear induction motor (LIM) with electromagnetic nonlinearity compensation to suppress nonlinear magnetic thrust reduction due the end effect. The (ECARC) is developed deal parametric uncertainties and uncertain nonlinearities that are widely present in LIM. employs a discontinuous projection‐type method estimate system parameters. disturbance bounded by critical value, which guarantees exponentially stable....
The surface mounting equipment (SME) is a critical and complex industrial system which require high-accuracy high-speed linear motion. In SME applications, the point-to-point motion main trajectory often subjected to parametric uncertainties uncertain nonlinearities. To achieve high performance of SME, adaptive robust control algorithm with dynamic friction compensation using LuGre model proposed in this paper. For uncertainties, uses discontinuous projection-type method estimate parameters....

Lower extremity rehabilitation robots play significantly important role in medicine, which aims to bring back the capabilities of patients' lower limbs because illness, injury and disease. However, controllability, energy consumption control precision robot motion remain difficult solve out. In many cases, electric motors are required have high output torque move entire machine legs along with human legs, while extravagant motor may lead excessive bending, fracture or other secondary...
The surface mounting equipment (SME) is critical and complex in electronic assembly process. key issue of SME to realize accurate positioning high-speed under the influence parametric uncertainties (e.g., unknown gravitational load) uncertain nonlinearities friction). For achieving this aim, adaptive robust control (ARC) based on dynamic LuGre model algorithm proposed. This uses a discontinuous projection-type online parameter adaptation method for parameters estimation. Compared with...
