| 1 | Highly Selective Biomimetic Flexible Tactile Sensor for Neuroprosthetics显示文摘Biomimetic flexible tactile sensors endow prosthetics with the ability to manipulate objects,similar to human hands.However,it is still a great challenge to selectively respond to static and sliding friction forces,which is crucial tactile information relevant to the perception of weight and slippage during grasps.Here,inspired by the structure of fingerprints and the selective response of Ruffini endings to friction forces,we developed a biomimetic flexible capacitive sensor to selectively detect static and sliding friction forces.The sensor is designed as a novel plane-parallel capacitor,in which silver nanowire-3D polydimethylsiloxane(PDMS)electrodes are placed in a spiral configuration and set perpendicular to the substrate.Silver nanowires are uniformly distributed on the surfaces of 3D polydimethylsiloxane microcolumns,and silicon rubber(Ecoflex^(■))acts as the dielectric material.The capacitance of the sensor remains nearly constant under different applied normal forces but increases with the static friction force and decreases when sliding occurs.Furthermore,aiming at the slippage perception of neuroprosthetics,a custom-designed signal encoding circuit was designed to transform the capacitance signal into a bionic pulsed signal modulated by the applied sliding friction force.Test results demonstrate the great potential of the novel biomimetic flexible sensors with directional and dynamic sensitivity of haptic force for smart neuroprosthetics. | Yue Li Zhiguang Cao Tie Li Fuqin Sun Yuanyuan Bai Qifeng Lu Shuqi Wang Xianqing Yang Manzhao Hao Ning Lan Ting Zhang | 2020 | Research2020，，1： | 4 |

| 8 | Stable epidermal electronic device with strain isolation induced by in situ Joule heating显示文摘Epidermal electronics play increasingly important roles in human-machine intetfaces.However,their efficient fabrication while maintaining device stability and reliability remains an unresolved challenge.Here,a facile in situ Joule heating method is proposed for fabricating stable epidermal electronics on a polyvinyl alcohol(PVA)substrate.Benefiting from the precise control of heating locations,the crystallization and enhanced rigidity of PVA are restricted to desired areas,leading to strain isolation of the active regions.As a result,the electronic device can be conformably attached to skin while showing negligible degradation in device performance during deformation.Based on this method,a flexible surface electromyography(sEMG)sensor with outstanding stability and highly comfortable wearability is demonstrated,showing high accuracy(91.83%)for human hand gesture recognition.These results imply that the fabrication method proposed in this research is a facile and reliable approach for the fabrication of epidermal electronics. | Zihao Wang Qifeng Lu Yizhang Xia Simin Feng Yixiang Shi Shuqi Wang Xianqing Yang Yangyong Zhao Fuqin Sun Tie Li Ting Zhang | 2021 | Microsystems & Nanoengineering2021，7，4： | 0 |
