Up to now, researches on the mobility–stretchability of semiconducting polymers are extensively investigated, but little attention was  paid to their morphology and field‐effect transistor characteristics under compressive strains, which is equally crucial in wearable electronic applications. In this work, a contact film transfer method is applied to evaluate the mobility–compressibility properties of conjugated polymers. A series of isoindigo–bithiophene conjugated polymers with symmetric carbosilane side chains (P(SiSi)), siloxane‐terminated alkyl side chains (P(SiOSiO)), and combined asymmetric side chains (P(SiOSi)) are investigated. Accordingly, a compressed elastomer slab is used to transfer and compress the polymer films by releasing prestrain, and the morphology and mobility evolutions of these polymers are tracked. It is found that P(SiOSi) outperforms the other symmetric polymers including P(Si─Si) and P(SiO─SiO), having the ability to dissipate strain with its shortened lamellar spacing and orthogonal chain alignment. Notably, the mechanical durability of P(SiOSi) is also enhanced after consecutive compress–release cycles. In addition, the contact film transfer technique is demonstrated to be applicable to investigate the compressibility of different semiconducting polymers. These results demonstrate a comprehensive approach to understand the mobility–compressibility properties of semiconducting polymers under tensile and compressive strains.

The major area of current interest in adaptive arrays in their application to problems arising in radar, sonar, and communication systems, where the designer almost invariably faces the problem of interference suppression. In general, for real time processing, the robustness, with respect to the changed environment, of the adaptive beamforming algorithm with rapid convergence rate is desired. In this paper, a new hybrid adaptive beamforming algorithm is derived in the discrete-cosine transformed domain for multiple jammers suppression. Overall performance improvement, in terms of convergence rate and the computational requirement, is addressed. From computer simulation results, it was found that the presented method outperformed the conventional Frost's linear constraints LMS algorithm, in terms of the capability of jammers suppression and the rate of convergence.

Recently, semiconducting polymers with intrinsic elasticity have garnered attention for their application in wearable devices. Herein, we synthesized a novel ABCBA-type miktoarm H-shaped copolymer (where A, B, and C represent...
