Dye-sensitized solar cells that adapt to different light conditions
Solar cells made of semi-transparent photovoltaic (PV) materials typically have a fixed optical transmission, which results in either high transparency or high efficiency, but rarely both. In order to perform optimally when integrated on buildings, however, they...
A reconfigurable ferroelectric field-effect transistor for frequency multiplication
Frequency multipliers, circuits that can produce signals with multiple frequencies, are essential components for a number of technological tools, particularly wireless communications systems. Most existing multipliers, however, are built using filtering and...
A new approach to control the stiffness and position of inflatable robots
Robots that are made of flexible materials that can be inflated have a number of desirable properties, including their light weight and high levels of compliance (i.e. the ability to undergo elastic deformation). These qualities make them ideal for completing tasks in...
KUBeetle-S: An insect-inspired robot that can fly for up to 9 minutes
Researchers at Konkuk University in South Korea recently created KUBeetle-S, a flying robot inspired by a species of horned beetle called Allomyrina dichotomy, which is among the largest insects on the planet. Allomyrina dichotomy weighs approximately 5 to 10 g and...
An origami-based robotic structure inspired by ladybird wings
Researchers at Seoul National University have recently developed a compact and lightweight origami structure inspired by ladybird beetles. In a paper published in Science Robotics they show how this structure can be used to build a winged jump-gliding robot....
A soft robotic finger fabricated using multi-material 3D printing
Researchers at Zhejiang University of Technology, Tianjin University, Nanjing Institute of Technology and Ritsumeikan University have recently created a soft robotic finger that integrates a self-powered curvature sensor using multi-material 3-D printing technology....
A new electrolyte design that could enhance the performance of Li-ion batteries
Most existing lithium-ion batteries (LIBs) integrate graphite anodes, which have a capacity of approximately 350 milliamp hours (mAh) per gram. The capacity of silicon anodes is almost 10 times higher than that of their graphite counterparts (around 2,800 mAh per...
A model for the origami-inspired folding of a tubular waterbomb
In recent years, research teams worldwide have been trying to apply origami-folding strategies to mechanical structures, as this could allow them to change their shape both rapidly and efficiently. A key advantage of origami, the Japanese art that entails folding...
A highly performing and efficient e-skin for robotic applications
Researchers at Technische Universität München in Germany have recently developed an electronic skin that could help to reproduce the human sense of touch in robots. This e-skin, presented in a paper published in MDPI's Sensors journal, requires far less computational...
