“…The facile and fast preparation of HSCs can potentially address the challenge of preparing large-scale functional surfaces for trapping liquids. [ 30 ] While most particle-based approaches to make superhydrophobic surfaces are based on deposition of matter, [ 11,[18][19][20][21]23 ] the formation of HSCs involves texturing through the removal of matter. This difference suggests the possibility of using wear as a complementary texturing mechanism that can improve the material's wear resistance rather than degrade it.…”

“…Subsequent regeneration of the surface yields a hierarchical texture that displays signifi cantly increased wear resistance and tolerates foot traffi c (>1000 steps by a 75 Kg person). By comparison, a state-of-the-art commercial solution (Neverwet) is shown to be ineffective after 100 steps.Similar reported approaches were based on the combustion of a certain kind of silicone but require hot-pressing [ 18 ] or microscale patterning [ 19 ] that are not scalable and do not provide good adhesion to most substrates. Other methods that have been proposed to make large-scale superhydrophobic surfaces suffer from other restrictions that limit their practical use.…”

“…15 Yong et al employed a point-by-point femtosecond laser scanning process to produce microwell arrays on PDMS lms. 20 Herein, we report the fabrication of superhydrophobic surfaces utilizing another substance produced from the combustion process, which will realize making full use of discarded silicone. 16 Owing to the natural hardness, good gas barrier properties and high thermal stability properties of silicon oxide, numerous investigations on the growth of a silicon oxide surface layer on a polysiloxane lm have arisen to explore their application in gas separation membranes, protective coatings for medical devices and microelectronics.…”

Utilizing the smoke emitted by discarded silicone combustion, a simple method of smoke deposition is presented for fabricating a superhydrophobic surface with outstanding water repellence, which exhibited a water contact angle of 164 AE 0.8 and a sliding angle of lower than 1 . In addition, the as-prepared surface possesses favourable heat, water impact and water immersion stabilities. Oil leakages seriously endanger both the environment and the social economy. By this simple smoke deposition method, a selective-wettability copper mesh has been fabricated to separate oil-water mixtures. The smokedeposited mesh achieved a high separation efficiency of over 93% for various oils, and showed excellent reusability, maintaining a high separation efficiency over 10 cycles. The water repellence of the used mesh can be refreshed by recoating with silicone and smoke deposition. This work provides a new strategy to utilize discarded silicone to fabricate superhydrophobic surfaces and oil-water separation meshes.Scheme 1 Schematic diagram showing the preparation of smokedeposited silicone coatings. 71330 | RSC Adv., 2015, 5, 71329-71335 This journal is

Owing to the advancement of interdisciplinary concepts, for example, wearable electronics, bioelectronics, and intelligent sensing, during the microelectronics industrial revolution, nowadays, extensively mature wearable sensing devices have become new favorites in the noninvasive human healthcare industry. The combination of wearable sensing devices with bionics is driving frontier developments in various fields, such as personalized medical monitoring and flexible electronics, due to the superior biocompatibilities and diverse sensing mechanisms. It is noticed that the integration of desired functions into wearable device materials can be realized by grafting biomimetic intelligence. Therefore, herein, the mechanism by which biomimetic materials satisfy and further enhance system functionality is reviewed. Next, wearable artificial sensory systems that integrate biomimetic sensing into portable sensing devices are introduced, which have received significant attention from the industry owing to their novel sensing approaches and portabilities. To address the limitations encountered by important signal and data units in biomimetic wearable sensing systems, two paths forward are identified and current challenges and opportunities are presented in this field. In summary, this review provides a further comprehensive understanding of the development of biomimetic wearable sensing devices from both breadth and depth perspectives, offering valuable guidance for future research and application expansion of these devices.
