“…Alternatively, components for power delivery can be engineered to be more lightweight and flexible in order to improve the portability of untethered soft devices. Recent work includes stretchable batteries 116,125 and elements that generate power by harvesting sweat in a stretchable electronic-skin-based biofuel cell 81 , incorporating flexible photovoltaics into a skin-conformal layer 126 or including thin stretchable triboelectric nanogenerators 127 .…”

Research in soft matter engineering has introduced new approaches in robotics and wearable devices that can interface with the human body and adapt to unpredictable environments. However, many promising applications are limited by the dependence of soft systems on electrical or pneumatic tethers. Recent work in soft actuation and electronics has made removing such cords more feasible, heralding a variety of applications from autonomous field robotics to wireless biomedical devices. Here we review the development of functional untethered soft robotics. We focus on recent advances in soft robotic actuation, sensing and integration as they relate to untethered systems, and consider the key challenges the field faces in engineering systems that could have practical use in real-world conditions.

“…[16][17][18][19] Thus, there is an obvious mismatch in the mechanics and form between the traditional rigid energy storage devices and emerging deformable electronic devices. [25][26][27][28][29] Among them, by virtue of their high power density, short recharging time, long durability, safety, and simple structure, stretchable supercapacitors (SCs) have shown great potential as compatible deformable power sources. [20][21][22][23][24] To date, a variety of novel deformable energy storage systems have been demonstrated for application as compatible power sources in flexible/ stretchable electronic devices.…”

Stretchable micropower sources with high energy density and stability under repeated tensile deformation are key components of flexible/wearable microelectronics. Herein, through the combination of strain engineering and modulation of the interlayer spacing, freestanding and lightweight MXene/bacterial cellulose (BC) composite papers with excellent mechanical stability and a high electrochemical performance are first designed and prepared via a facile all‐solution‐based paper‐making process. Following a simple laser‐cutting kirigami patterning process, bendable, twistable, and stretchable all‐solid‐state micro‐supercapacitor arrays (MSCAs) are further fabricated. As expected, benefiting from the high‐performance MXene/BC composite electrodes and rational sectional structural design, the resulting kirigami MSCAs exhibit a high areal capacitance of 111.5 mF cm −2 , and are stable upon stretching of up to 100% elongation, and in bent or twisted states. The demonstrated combination of an all‐solution‐based MXene/BC composite paper‐making method and an easily manipulated laser‐cutting kirigami patterning technique enables the fabrication of MXene‐based deformable all‐solid‐state planar MSCAs in a simple and efficient manner while achieving excellent areal performance metrics and high stretchability, making them promising micropower sources that are compatible with flexible/wearable microelectronics.

“…Thus, the construction of flexible, wearable, highly sensitive, and lightweight FTSs based on rGO is a top priority. The integration of energy harvest, storage, and conversion into a single configuration has attracted abundant attention in recent years 34, 35, 36, 37, 38. Our target in adopting this strategy is to integrate FTSs with FASCs to fabricate a device that can provide stable output power to FTSs.…”

Wearable fiber‐shaped electronic devices have drawn abundant attention in scientific research fields, and tremendous efforts are dedicated to the development of various fiber‐shaped devices that possess sufficient flexibility. However, most studies suffer from persistent limitations in fabrication cost, efficiency, the preparation procedure, and scalability that impede their practical application in flexible and wearable fields. In this study, a simple, low‐cost 3D printing method capable of high manufacturing efficiency, scalability, and complexity capability to fabricate a fiber‐shaped integrated device that combines printed fiber‐shaped temperature sensors (FTSs) with printed fiber‐shaped asymmetric supercapacitors (FASCs) is developed. The FASCs device can provide stable output power to FTSs. Moreover, the temperature responsivity of the integrated device is 1.95% °C−1.
