Flexible triboelectric generator

Conventionally, engineers have employed rigid materials to fabricate precise, predictable robotic systems, which are easily modelled as rigid members connected at discrete joints. Natural systems, however, often match or exceed the performance of robotic systems with deformable bodies. Cephalopods, for example, achieve amazing feats of manipulation and locomotion without a skeleton; even vertebrates such as humans achieve dynamic gaits by storing elastic energy in their compliant bones and soft tissues. Inspired by nature, engineers have begun to explore the design and control of soft-bodied robots composed of compliant materials. This Review discusses recent developments in the emerging field of soft robotics.

Design, fabrication and control of soft robots

Wearable sensor technologies are essential to the realization of personalized medicine through continuously monitoring an individual's state of health. Sampling human sweat, which is rich in physiological information, could enable non-invasive monitoring. Previously reported sweat-based and other non-invasive biosensors either can only monitor a single analyte at a time or lack on-site signal processing circuitry and sensor calibration mechanisms for accurate analysis of the physiological state. Given the complexity of sweat secretion, simultaneous and multiplexed screening of target biomarkers is critical and requires full system integration to ensure the accuracy of measurements. Here we present a mechanically flexible and fully integrated (that is, no external analysis is needed) sensor array for multiplexed in situ perspiration analysis, which simultaneously and selectively measures sweat metabolites (such as glucose and lactate) and electrolytes (such as sodium and potassium ions), as well as the skin temperature (to calibrate the response of the sensors). Our work bridges the technological gap between signal transduction, conditioning (amplification and filtering), processing and wireless transmission in wearable biosensors by merging plastic-based sensors that interface with the skin with silicon integrated circuits consolidated on a flexible circuit board for complex signal processing. This application could not have been realized using either of these technologies alone owing to their respective inherent limitations. The wearable system is used to measure the detailed sweat profile of human subjects engaged in prolonged indoor and outdoor physical activities, and to make a real-time assessment of the physiological state of the subjects. This platform enables a wide range of personalized diagnostic and physiological monitoring applications.

Stretchable electronics: epidermal electronics with advanced capabilities in near-field communication (small 8/2015).

As an outstanding member in the oxide nanowire family, ZnO nanowire is widely studied for its optical, semiconductive, and piezoelectric properties. PbZr x Ti 1-x O 3 (PZT), usually in the form of polycrystalline thin films, is known for its high piezoelectric coefficient and is an ideal material as actuator. In this review, we first briefly introduce the rational growth of ZnO and PZT nanowire arrays by seedless wet chemical methods. Utilizing the ordered ZnO nanowires grown on p-type substrates, we next present an array of single ZnO nanowire-based blue/near-UV light-emitting diodes (LEDs), including their fabrication process, electroluminescence (EL) spectra, and external quantum efficiency. Finally, we discuss the piezoelectric ZnO and PZT nanowire-enabled three-dimensionally integrated direct- and alternating-current nanogenerators, and their primary roles in self- powered nanosystems and for powering personal microelectronics.

Oxide nanowire arrays for energy sciences

Publisher Summary This chapter provides an overview of zinc oxide (ZnO) nanowire synthesis strategies pertinent to flexible organic substrates. The different strategies have been used to grow ZnO nanowire arrays on flat flexible substrates, such as polyimide and polystyrene, and curved flexible substrates, such as microfibers. By using electron beam lithography (EBL) or photolithography, a patterned growth of ZnO nanowire arrays could also be achieved on both flat substrates and microfibers. Furthermore, based on vertically aligned ZnO nanowire arrays on the flexible substrates, innovative nanotechnology-enabled methods for converting mechanical energy into electrical energy have been demonstrated, with the aim of building self-powered nanosystems. The focus was on the fundamental mechanism of the piezoelectricity and nanogenerators. The core of the nanogenerator is based on coupling the piezoelectric and semiconducting properties of ZnO nanowires and the presence of a Schottky barrier at the metal–semiconductor interface.
