“…[1][2][3][4][5][6] Materials decorated with self-healing feature could boost the lifetime of products and build new potentials in various areas. 7 Selfhealing conductors are currently attracting a significant number of studies, [8][9][10][11][12][13][14][15][16] particularly for advanced electronic applications, including chemical sensors, 17 thermal sensors, 18 supercapacitors, [19][20][21] lithium-ion batteries, 2 and electronic skin. 7,22 Similarly, flexible conductors play an important role in the emerging fields, such as prosthetics, soft robotics, stretchable displays and human machine interfaces.…”

Intrinsic self-healing polyborosiloxane (PBS) and its multi-walled carbon nanotube (MWCNT)-reinforced nanocomposites were synthesized from hydroxyl terminated poly(dimethylsiloxane) (PDMS) and boric acid at room temperature. The formation of Si-O-B moiety in PBS was confirmed by Fourier transform infrared spectroscopy. PBS and its MWCNT-reinforced nanocomposites were found possessing water or methanol activated mechanically adaptive behaviors; the compressive modulus decreased substantially when exposed to water or methanol vapor and recovered their high value after the stimulus was removed. The compressive modulus was reduced by 76%, 86%, 90% and 83% for neat PBS and its nanocomposites containing 3.0 wt.%, 6.2 wt.% and 13.3 wt.% MWCNTs, respectively, in water vapor, and the modulus reduction activated by methanol vapor was greater than by water vapor. MWCNTs at higher contents acted as a continuous electrical channel in PBS offering electrical conductivity, which was up to 1.21 S/cm for the nanocomposite containing 13.3 wt.% MWCNTs. The MWCNT-reinforced PBS nanocomposites also showed excellent mechanically and electrically self-healing properties, moldability and adhesion to PDMS elastomer substrate. These properties enabled a straightforward fabrication of self-repairing MWCNT/PBS electronic circuits on PDMS elastomer substrates.

“…258 This enables them to deform and stretch in response to stress in a reversible manner, which makes them ideal candidates for stretchable and self‐healable electronics 259, 260, 261. Especially, in recent years, there have been tremendous advancements in the emerging technology of stretchable electronics based on liquid metals such as mercury and gallium oxide (Ga 2 O 3 ) 262.…”

Blending Electronics with the Human Body: A Pathway toward a Cybernetic Future

et al. 2018

At the crossroads of chemistry, electronics, mechanical engineering, polymer science, biology, tissue engineering, computer science, and materials science, electrical devices are currently being engineered that blend directly within organs and tissues. These sophisticated devices are mediators, recorders, and stimulators of electricity with the capacity to monitor important electrophysiological events, replace disabled body parts, or even stimulate tissues to overcome their current limitations. They are therefore capable of leading humanity forward into the age of cyborgs, a time in which human biology can be hacked at will to yield beings with abilities beyond their natural capabilities. The resulting advances have been made possible by the emergence of conformal and soft electronic materials that can readily integrate with the curvilinear, dynamic, delicate, and flexible human body. This article discusses the recent rapid pace of development in the field of cybernetics with special emphasis on the important role that flexible and electrically active materials have played therein.

“…The carbon nanotubes may then repair the circuit and reestablish its function. Alternatively, the same effect is reached through the inclusion of microcapsules that are filled with a liquid metal (gallium-indium) [91,92]. A combination of bigger and smaller microcapsules may optimise both reliability and conductivity after repair.…”

AbstractComplexity Engineering encompasses a set of approaches to engineering systems which are typically composed of various interacting entities often exhibiting self-* behaviours and emergence. The engineer or designer uses methods that benefit from the findings of complexity science and often considerably differ from the classical engineering approach of “divide and conquer”.This article provides an overview on some very interdisciplinary and innovative research areas and projects in the field of Complexity Engineering, including synthetic biology, chemistry, artificial life, self-healing materials and others. It then classifies the presented work according to five types of nature-inspired technology, namely: (1) using technology to understand nature, (2) nature-inspiration for technology, (3) using technology on natural systems, (4) using biotechnology methods in software engineering, and (5) using technology to model nature. Finally, future trends in Complexity Engineering are indicated and related risks are discussed.
