Team develops seaweed-derived hydrogel for wound healing
The seaweed-based hydrogel reportedly achieves physical properties that are different from those of conventional hydrogels, which tend to interfere with the wound healing process by stretching and expanding the wound itself thanks to adhesives.
Spider silk inspires polymer for connecting biological tissues with electronic devices
Taking inspiration from spider-silk draglines, which shrink in the presence of high humidity or water, the team created a polymer featuring the crystalline properties like those in the silk draglines.
AI model predicts COVID-19 variant waves
The researchers explained that the patterns revealed by the analysis were used to create the machine-learning powered risk assessment model.
Polymers that kill bacteria developed by Texas A&M
Researchers designed a positively charged molecule that can be stitched repeatedly to create a larger molecule composed of the same repeating charged motif via a catalyst called AquaMet.
Team develops 'electronic tongue' technology
The electronic tongue features sensors and deep-learning technology for accurately measuring saltiness, sourness, bitterness and sweetness simultaneously.
Ingestible, vibrating device promises to prevent overeating
The capsule is designed to vibrate once in the stomach, thereby activating the stretch receptors that sense when the stomach is distended, thus giving the imaginary sense of fullness.
New coating promises to keep bacteria from clinging to toilets
To create the coating, researchers ground poly(dimethylsiloxane) (PDMS), which is a silicone oil, in a ball mill for about 60 minutes.
A robotic catheter that promises to make heart surgeries safer
A team of Boston University engineers and physicians has created a robotic catheter capable of shape shifting.
Patch promises to treat congenital heart defects
The team created a tissue-engineered myocardial patch via electrospinning, wherein electricity is applied to fluid solutions to produce nanofibers to form a scaffold, which is eventually injected with living cells that subsequently become the patch.
A new 3D-printed surgical implant destroys bacteria
The development promises to potentially improve infection control in common surgeries like hip and knee replacements, wherein bacterial colonization on the implants threatens surgical outcomes and leads to potential implant failure.
DuPont introduces conductive tape for use as dry electrode in biosignal monitoring
The silicone-based soft skin conductive tape will support the development of biosignal-monitoring devices with stable data quality and high patient comfort.
New fiber is both conductive and flexible
Designed for wearable e-textiles, the fiber was created by combining one solution composed of the synthetic polymer polyaniline, which has conductive properties, and a second solution composed of dissolved cotton cellulose from recycled T-shirts.
This mind-reading AI can turn thoughts into text
To develop the device, participants were tasked with silently reading passages of text while wearing an electroencephalogram (EEG)-equipped cap, which recorded electrical brain activity through the wearer’s scalp.
DNA-based nanobots replicate themselves via UV light
Composed of just four DNA strands, the tiny DNA bots can reportedly replicate themselves one at a time by using their structure as a possible template.
How to use a gauge pressure sensor to measure negative pressure
Discover the utility of gauge pressure sensors in measuring negative pressure for medical and industrial applications.
A toothpaste that promises to treat peanut allergies
The toothpaste is expected to deliver allergenic peanut proteins to the allergic person’s oral cavity, thereby gradually desensitizing the user to the allergen.
Team develops long-jumping insect-inspired robots
Taking inspiration from the leaping ability of locusts, the monolithic elastomeric robot features coiled artificial muscle actuators and projection additive printing.
Hand gesture recognition technologies for healthcare and security
Hand gesture recognition technologies have the potential to enhance the naturalness and intuitiveness of human-computer interactions.
A seed-sized radar sensor detects microscopic movements
The device relies on millimeter-wave — an electromagnetic frequency that ranges from 30 gigahertz to 300 gigahertz and is located between microwaves and infrared — radar technology.
Video: Microfluidic platform models disease in human organs
The device monitors interactions between up to eight unique organ tissue cultures for extended periods of time to replicate how actual organs will respond.
