Fiber is a symbol of human civilization, being ubiquitous but obscure in society over most of history. Fiber has been revived upon the advent of fiber‐based electronic devices in the past two decades. This is due to its desirable lightweight, flexible, and conformable characteristics, which enable it to play a fundamental role in the electronic and information era. Numerous fiber‐based electronic devices have sprung up in energy conversion, energy storage, sensing, actuation, etc. A possibility is thereby conceived that they can be integrated into smart systems compatible with the human body, consisting of biotic fiber‐based organs and tissues, which possess similar but more advanced functions. However, the design of mono‐/multifibers, the construction of fiber‐based devices, and the integration of these smart systems represent great challenges in fundamental understanding and practical implementation. A systematic review of the current state of the art with respect to the design and fabrication of electronic fiber materials, construction of fiber‐based devices, and integration of smart systems is presented. In addition, limitations of current fiber‐based devices and perspectives are explored toward potential and promising smart integration.

Next generation wearable electronics require stretchable dielectrics. There has been significant effort to characterize and improve the components of dielectric composites for use in these devices. In this work, a new stretchable dielectric material, composited by silver nanoparticles (Ag NPs), nickel nanoparticles (Ni NPs), and polydimethylsiloxane (PDMS), is prepared and characterized. The alternating arrays of Ag NPs groups and Ni NPs groups in the three-dimensional matrix of PDMS function as micro capacitors and prevent current percolation. Compared with PDMS alone, the alternating arrays exhibit a dielectric constant (k) that is increased by 1146% and can reach 35.13, with dielectric loss as low as 0.009. Slightly lower k and larger dielectric loss appear at high frequencies. The material exhibits negative temperature dependence, and the composition ratio affects the dielectric properties. The strain at break is 139.68% and the elastic modulus is as low as 3.57 kPa. By controlling the type, size and dispersion of metal nanoparticles in PDMS matrix, a parallel-plate capacitor with constant capacitance is achieved, demonstrating the dependence of the dielectric constant on the applied strain. Moreover, by replacing the parallel plates with cylindrical fibers, a capacitive strain sensor was demonstrated. After hundreds of stretching-releasing cycles, the dielectrics work normally. The excellent properties of this material suggest its significant potential for use in wearable electronics.

Fiber‐shaped batteries are widely explored for a variety of important fields such as wearable electronics, information technology, internet of things, and public health. However, it remains difficult to simultaneously achieve high energy density, power density, and safety, which has largely limited their promising applications. Here, a new type of fiber‐shaped Ni//Bi batteries with remarkable electrochemical performances is created from hierarchically 3D electrodes, where reduced graphene oxide sheets framed with Bi serve as the anode while reduced graphene oxide sheets wrapped with nickel oxide/nickel function as the cathode. The fiber‐shaped Ni//Bi batteries show high energy density of 43.35 Wh kg−1 or 26.01 mWh cm−3 and high power density of 6600 W kg−1 or 3.96 W cm−3 with 96% capacity retention after 10 000 cycles. They are also safe with the use of aqueous electrolyte and can be further woven into the next‐generation flexible textile‐type power system. This work provides a general and efficient strategy to develop high‐performance batteries by designing hierarchically structured electrodes.
