A droplet-sensing bionic e-skin that could further enhance robotic perception
In recent years, many research teams have been trying to design artificial skins with electronic properties for humanoid robots, smart prosthetics and other bio-inspired systems. These skins could sense the textures and tactile properties of objects, allowing various...
A flapping microrobot inspired by the wing dynamics of rhinoceros beetles
The wing dynamics of flying animal species have been the inspiration for numerous flying robotic systems. While birds and bats typically flap their wings using the force produced by their pectoral and wing muscles, the processes underlying the wing movements of many...
New yttrium-doping strategy enhances 2D transistors
Electronics engineers and materials scientists have been trying to identify materials that could help to boost the performance of electronics further, overcoming the inherent limitations of silicon-based transistors. Two-dimensional (2D) semiconductors have...
A weeding robot that can autonomously remove seedlings
Robotic systems are already being deployed in various settings worldwide, assisting humans with a highly diverse range of tasks. One sector in which robots could prove particularly advantageous is agriculture, where they could complete demanding manual tasks faster...
A new approach to efficiently model the acoustics of an environment
Augmented reality (AR) and virtual reality (VR) are designed to artificially reproduce the experience of navigating certain environments. In recent years, videogame and entertainment companies have been producing increasingly immersive content that can be accessed...
An approach to enable both locomotion and manipulation in a snake-inspired robot
Snake-inspired robots could have various advantages over conventional wheeled or legged robots. For instance, slithering robots can adapt the shape of their body, enter narrow spaces, and move freely in environments that are inaccessible to both humans and other robots.
Electronics engineers successfully integrate MoS₂ transistors on a 200 mm wafer
In recent years, electronics engineers have been trying to design increasingly sophisticated transistors that can be scaled down to smaller sizes. Given the limitations of conventional silicon-based field effect transistors (FETs), some teams have been experimenting...
Floating photovoltaics could limit Africa’s future reliance on hydro-generated energy
Floating photovoltaics (FPV), also known as floating solar farms, are photovoltaic systems that can be deployed on the sea's surface or on other bodies of water. While their environmental impact is still the topic of debate worldwide, these systems could be highly...
A promising three-terminal diode for wireless communication and optically driven computing
Two-terminal devices are electronic components connected to electrical circuits via two electrical terminals. Although these components are the key building blocks of most existing devices, they can limit a system's performance and functions.
