The development of modern robotics has triggered increasing interest in developing artificial tactile sensory systems. However, the tactile mechanism in the design process has been highly limited to ...experimental tests that are expensive and time-consuming. This work is concerned with the development of using virtual tests for tactile sensory response prediction and design, which includes numerical simulation settings, database creation, response regression and interpolation, and sensor sensitivity designs. Experimental verifications and numerical demonstrations are performed based on the NUS NeuTouch sensors. The potential of using virtual tests to design new tactile sensors to improve response linearity is illustrated.

Although polymers have been studied for well over a century, there are few examples of covalently linked polymer crystals synthesised directly from solution. One-dimensional (1D) covalent polymers ...that are packed into a framework structure can be viewed as a 1D covalent organic framework (COF), but making a single crystal of this has been elusive. Herein, by combining labile metal coordination and dynamic covalent chemistry, we discover a strategy to synthesise single-crystal metallo-COFs under solvothermal conditions. The single-crystal structure is rigorously solved using single-crystal electron diffraction technique. The non-centrosymmetric metallo-COF allows second harmonic generation. Due to the presence of syntactic pendant amine groups along the polymer chains, the metallopolymer crystal can be further cross-linked into a crystalline woven network.
The marriage of dynamic covalent chemistry (DCC) and coordination chemistry is a powerful tool for assembling complex architectures from simple building units. Recently, the synthesis of woven ...covalent organic frameworks (COFs) with topologically fascinating structures has been achieved using this approach. However, the scope is highly limited and there is a need to discover new pathways that can assemble covalently linked organic threads into crystalline frameworks. Herein, we have identified branching pathways leading to the assembly of three‐dimensional (3D) woven COFs or one‐dimensional (1D) metallo‐COFs (mCOFs), where the mechanism is underpinned by the absence or presence of ligand exchange.
What far from tangled webs we weave: By combining dynamic covalent chemistry (DCC) and coordination chemistry, divergent paths for the construction of three‐dimensional (3D) woven covalent organic frameworks (COFs) or one‐dimensional (1D) metallo‐COFs (mCOFs) are identified. The paths are distinguished by the absence or presence of ligand exchange.
