Integrated digital inverters based on two-dimensional anisotropic ReS2 field-effect transistors.

Abstract: Many two-dimensional materials exhibit isotropic properties, but anisotropy can extend the functionality of future devices. Here, the authors fabricate field-effect transistors from single and few-layer rhenium disulfide and observe an anisotropic ratio of three to one along the two principle axes

A highly sensitive, self-powered triboelectric auditory sensor for social robotics and hearing aids

Abstract: The auditory system is the most efficient and straightforward communication strategy for connecting human beings and robots. Here, we designed a self-powered triboelectric auditory sensor (TAS) for constructing an electronic auditory system and an architecture for an external hearing aid in intelligent robotic applications. Based on newly developed triboelectric nanogenerator (TENG) technology, the TAS showed ultrahigh sensitivity (110 millivolts/decibel). A TAS with the broadband response from 100 to 5000 hertz was achieved by designing the annular or sectorial inner boundary architecture with systematic optimization. When incorporated with intelligent robotic devices, TAS demonstrated high-quality music recording and accurate voice recognition for realizing intelligent human-robot interaction. Furthermore, the tunable resonant frequency of TAS was achieved by adjusting the geometric design of inner boundary architecture, which could be used to amplify a specific sound wave naturally. On the basis of this unique property, we propose a hearing aid with the TENG technique, which can simplify the signal processing circuit and reduce the power consuming. This work expresses notable advantages of using TENG technology to build a new generation of auditory systems for meeting the challenges in social robotics.

Exploring teachers’ perceived self efficacy and technological pedagogical content knowledge with respect to educational use of the World Wide Web

Abstract: Research in the area of educational technology has claimed that Web technology has driven online pedagogy such that teachers need to know how to use Web technology to assist their teaching. This study provides a framework for understanding teachers’ Technological Pedagogical Content Knowledge-Web (TPCK-W), while integrating Web technology into their pedagogical practice. Furthermore, contemporary educational researchers have highlighted the significance of teachers’ self-efficacy, conceptualized as the teachers’ perceptions of their own competence at teaching, and related to instructional strategies as well as teaching effectiveness. The major purpose of this study was to investigate teachers’ perceived self-efficacy in terms of their TPCK-W. This study aimed to develop a new questionnaire, namely the Technological Pedagogical Content Knowledge-Web (TPCK-W) Survey to explore teachers’ self-efficacy in terms of their TPCK-W, and additionally to assess their attitudes toward Web-based instruction. The participants in this study were 558 teachers from elementary school to high school level in Taiwan. Both exploratory and confirmatory factor analyses indicated that the TPCK-W survey developed in this study has satisfactory validity and reliability characteristics. The results indicate a lack of general knowledge about Web-related pedagogy amongst the teachers surveyed. The correlations between teachers’ self-efficacy in terms of their TPCK-W, their attitudes regarding Web-based instruction, and their background variables were also examined. Correlations were found between self-efficacy and positive attitudes to web-based instruction. Older and more experienced teachers were found to have lower levels of self-efficacy with respect to TPCK-W, though teachers with more experience of using the web (including for instruction) had higher levels of self-efficacy with respect to TPCK-W.
