In article number 2000128, Youhui Lin, Xiang Yang Liu, and co‐workers successfully create 3D “molecular springs” networks by establishing crosslinks of scattered wool keratin. The as‐prepared networks display unique elasticity, high resistance fatigue, fast self‐recovery, and ultralow effective elastic modulus. Due to the fascinating features, such wool keratin mediated materials can be used in the...
Wool keratin (WK) consists of a large number of α‐helices, which are just like many molecular‐scale springs. Herein, the construction of 3D WK molecular spring networks are reported by cross‐linking individual WK molecules via a Michael addition reaction. The as‐prepared springs display a superior recovery capability with unusual nonlinear elasticity, very low dissipative energy, and turntable elastic...
This study reports a novel approach to implement the CNTs (carbon nanotubes)-based flexible capacitive strain sensor and the detection of bending strain is demonstrated. The merits of presented design are as follows, (1) employ the aligned CNTs (50μm~100μm in height) as interdigital finger electrodes to increase sensing area and initial capacitance, (2) the 3D CNTs electrodes and electrical routings,...
