Researchers build a biodegradable mini-capacitor that consists of carbon, cellulose, glycerin, and table salt — and it works reliably.
Results for "sensors"
A robot that smiles back
Researchers teach robots to make appropriate reactive human facial expressions, an ability that could build trust between humans and their robotic co-workers and care-givers.
Scientists develop eco-friendly pollen sponge to tackle water contaminants
This pollen sponge can absorb oil contaminants, such as gasoline and motor oil, at a rate comparable to commercial oil absorbents
Even without a brain, metal-eating robots can still search for food
The “metal-eating” robot can follow a metal path without using a computer or needing a battery.
DraBot: A soft robotic dragonfly that senses and monitors its environment
Electronics-free DraBot uses air pressure, microarchitectures, and self-healing hydrogels to watch for changes in pH, temperature, and the presence of contaminants.
A spotlight on robots helps them turn “feeling” into movement
Researchers recreate the somatic nervous system in robots, allowing them to convert feeling into movement under different stimuli.
New approach keeps outdoor wearable electronics cool
“Cool gadgets” takes on new meaning as scientists develop a radiative cooler that keeps wearable device temperature down, even under direct sunlight.
Solar-powered robot lifts 25x its own weight
A liquid-based, solar-powered soft robot has this writer dreaming of its potential applications in space explorations and beyond.
Temporary light-emitting tattoos, anyone?
A new fabrication method allows researchers to create ultra-thin OLED materials that can be applied to the skin using temporary tattoo paper.
How do you sample blood in a non-invasive way?
Graphene-based biosensors incorporated in arrays of microneedles are emerging as an alternative to hypodermic needles and could be the next generation of blood sampling devices.
