Abstract(#br)All-solution-processed, easily-made, flexible multi-walled carbon nanotube (MWCNT)/polydimethylsiloxane (PDMS)-based electrodes were fabricated and used for electrochemical DNA sensors. These electrodes could serve as a recognition layer for DNA, without any surface modification, through π–π interactions between the MWCNTs and DNA, greatly simplifying the fabrication process for DNA sensors.

Abstract(#br)We investigate the use of stiffness-controlled polydimethylsiloxane (PDMS) endplates with Young's modulus of 7.50 × 10 5 Pa and 8.68 × 10 5 Pa for improving the performance of flexible fuel cells. The maximum power densities of stacks with PDMS endplates with Young's modulus of 7.50 × 10 5 Pa and 8.68 × 10 5 Pa are 82 mWcm −2 and 117 mWcm −2 , respectively. The flexible fuel cells produce a maximum absolute power of 1.053 W (i.e., the power density is 117 mWcm 2 ) under a bending radius of 15 cm.

Abstract(#br)This study presents a novel multifunctional tactile sensor to mimetic the human skin with high sensitive, flexible, and temperature measurable performances. The substrate is flexible due to the material property of the Polydimethylsiloxane (PDMS). The top electrode and bottom electrode layers are interlocked by the zinc oxide (ZnO) nanorods, which is vertically growing on the top of PDMS, providing high sensitivity for the measurement of the contact force and environment temperature.

摘要 将钛酸钡( BT )纤维和BT粉末分别与聚二甲基硅氧烷( PDMS )基体相和叉指电极( IDE )结合，制备了一种柔性压电纳米发电机( FPENG )。采用静电纺丝法制备BT纤维。采用X射线衍射( XRD )技术对样品进行物相分析。采用Rietveld细化方法，可以确定BT纤维的四方结构。扫描电镜结果表明，BT纤维表面不光滑，说明聚合物和有机前驱体已被去除。采用50 % BT纤维制备的FPENG，其开路电压约为12 V，短路电流约为1μA，且FPENG内部分散相的影响对其输出性能的提高起到了一定的作用。该FPENG装置在退化前可运行5k次。通过连续加压至40k次，输出电压趋于零值。研究发现，机械疲劳效应与IDEs与PDMS界面在压制过程中产生的损伤有关。研究结果可为进一步设计FPENG器件的材料和器件结构，获得高性能和稳定性提供指导。

Abstract(#br)In this study, we present a dimension-controllable 3D biomedical microelectrode based on low melting point metals (Bi/In/Sn/Zn alloy) applied using the phase transition method. We have established a process, in which the liquid metal is pumped through a syringe needle of the dispensing system to form a needle shape after cooling at room temperature. PDMS (polydimethylsiloxane) was chosen as the substrate of the electrode as it is amenable to micro-molding and has excellent flexibility.

采用Ni-Zr合金薄膜氢敏传感器、柔性、Ni-Zr、PDMS、薄膜，通过旋涂和直流磁控溅射制备了三层$PMMA/Ni_{64}Zr_{36}/PDMS$型氢敏传感器。PDMS (聚二甲基硅氧烷)作为柔性基底，PMMA (聚甲基丙烯酸甲酯)薄膜沉积在$Ni_{64}Zr_{36}$合金层上，赋予传感器较高的氢选择性。所制备的传感器在高氢浓度( 99.9 % )下的氢传感能力和响应时间均表现出20 %的电阻变化，优于常规Pd基氢传感器，难以在高氢浓度环境下使用。在氢气浓度为5 %时，电的电阻约为1.4 %，这是一种类似于$Pd_{77}Ag_{23}$传感器的电阻。尽管采用低成本的$Ni_{64}Zr_{36}$合金作为主要传感元件，但在高浓氢气气氛下仍能获得与现有Pd传感器类似的性能。通过优化包括各层厚度和Ni-Zr合金薄膜成分的氢检测灵敏度，提出的Ni-Zr基氢传感器可以替代Pd基氢传感器。

Electronic skin (e‐skin), an important part toward the realization of artificial intelligence, has been developing through comprehending, mimicking, and eventually outperforming skin in some aspects. Most of the e‐skin substrates are flexible polymers, such as polydimethylsiloxane (PDMS). Although PDMS was found to be biocompatible, it is not suitable for long‐time wearing due to its air impermeability.

本文提出了一种用于X和Ku波段应用的光学透明、柔性微波吸收器。该吸收剂采用光学透明的ITO涂复PET薄膜来产生欧姆损耗，聚二甲基硅氧烷作为介质基板来实现光学透明和柔性。该结构的新颖之处在于其光学透明性和灵活性，与以往报道的吸收体相比，吸收带宽和最小厚度都有所增加。该吸收剂在8.00 ~ 20.70 GHz的频率范围内具有吸收率( 90 %以上)。吸收体的厚度为0.196λg (其中λg对应于介电常数εr的导波波长)。提出了一种与全波模型吻合较好的等效电路模型。
