There has been an emerging interest in stretchable power sources compatible with flexible/wearable electronics. Such power sources must be able to withstand large mechanical strains and still maintain function. Here we report a highly stretchable H3PO4-poly(vinyl alcohol) (PVA) polymer electrolyte obtained by optimizing the polymer molecular weight and its weight ratio to H3PO4 in terms of conductivity and mechanical properties. The electrolyte demonstrates a high conductivity of 3.4 x 10-3 S cm-1, and a high fracture strain at 410% elongation. It is mechanically robust with a tensile strength of 2 MPa and a Young's modulus of 1 MPa, and displays a small plastic deformation (5%) after 1000 stretching cycles at 100% strain. A stretchable supercapacitor device has been developed based on buckled polypyrrole electrodes and the polymer electrolyte. The device shows only a small capacitance loss of 5.6% at 30% strain, and can retain 81% of the initial capacitance after 1000 cycles of such stretching.

Conventionally, engineers have employed rigid materials to fabricate precise, predictable robotic systems, which are easily modeled 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 like 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.

The nanostructure and the dimension of materials greatly affect their performance and function. It is important to develop synthesis strategies that enable the control of the materials' morphology and structure and further reduce their size. In the present work, we report a novel synthesis approach that utilizes Si nanoparticles for synthesizing ultrafine MnO nanowires. The resulting nanostructure comprises MnO nanowires with a diameter of~5-10 nm embedded in an amorphous carbon matrix. X-ray diffraction patterns and high-resolution transmission electron microscopy images clearly reveal the growth mechanism of nanowires. As an anode material for the lithium-ion battery, the nanostructure exhibits excellent charge transfer kinetics and extremely high electrochemical performance, including reversible specific capacities of 285.9 mA h g − 1 at 30 A g − 1 and 757.4 mA h g − 1 at 1 A g − 1 after 1000 cycles. X-ray absorption fine structure (XAFS) confirms that the enhanced performance is related to the increase of the ordering of the O 2 − ions in the MnO structure during the charge/discharge processes. This novel synthesis strategy may inspire studies of other transition-metal-oxide nanomaterials with special orientation to tune their physical chemistry properties.
