Food-safe microneedles incorporated into a new smart label can effectively collect samples from packaged food and inform consumers about its quality in real time.
Sensors
Mussels and chameleons inspire a new type of sensor
Scientists design a stretchable, adhesive, self-healing material that can change color as a result of movement for real-time motion sensors.
New smart fabrics from bioactive inks monitor body and environment
Bioactive inks printed on wearable textiles can map conditions over the entire surface of the body, including possible pathogens.
Over-crowding particles drives their motion
Using an asymmetric sawtooth-shaped potential, researchers achieve transport of tiny molecules driven by particle crowding.
Gentle laser processing of perovskites at the nanoscale
Scientists have developed a method for precise, fast, and high-quality laser processing of halide perovskites, promising light-emitting materials for solar energy, optical electronics, and metamaterials.
A foldable and washable luminescent film to better visualize infrared radiation
Near-infrared sensors and displays developed based on the maximized efficiency of optical wavelength conversion.
How do you power billions of sensors? By converting waste heat into electricity
Researchers at Osaka University are helping to power portable sensors that do not use batteries by generating electricity from heat that is otherwise wasted.
The soft touch of intelligent, robotic systems
A new, flexible, and self-powered sensor made by magnetoelectric materials can convert mechanical stimuli to electrical signals for robots with a “soft touch”.
