Sweat-powered sticker transforms cups into health monitors
The flexible sticker instead adheres to the outside of a drinking cup, where it collects trace amounts of sweat as a person grips the cup.
Seaweed-based casings may replace plastic in home test kits
The team is hoping to create seaweed-based housings to replace traditional petroleum plastics without changing the way such diagnostic lateral flow tests work.
New material helps teeth regrow and fortify enamel
The gel, which is fluoride free, works by replicating the features of the natural proteins that encourage the growth of dental enamel in infancy.
Injectable hydrogels offer a new way to track biological activity within the body
The team at Washington University is working to develop granular hydrogels comprised of microparticles that could potentially be injected, spread over tissues or used to encapsulate cells to monitor or stimulate biological activity.
Modern approaches to bioprinting technology
Bioprinting combines principles from biology, materials science and manufacturing to create living structures from cells. Instead of printing with plastic or metal, these systems use bioinks made from cells and hydrogels to build tissue-like materials layer by layer.
Skin-like organic biosensors enable real-time health monitoring
The new biosensors, which are devices capable of converting biological responses into measurable electrical signals, feature a unique design that promises to enable the collection of reliable recordings under assorted environmental conditions.
Soft, air-powered robotic elbow exoskeleton eases muscle effort, reduces workload
Designed particularly for workers whose jobs involve hours of lifting and repetitive motion and to prevent future musculoskeletal disorders, the Pneumatically Actuated Soft Elbow Exoskeleton (PASE) is a lightweight silicone "pneumatic actuator."
Lead-free silicon patch offers clearer, eco-friendly ultrasound imaging
According to the researchers, their ultrasound patch has demonstrated superior performance beyond that of conventional high-cost, lead-based ultrasound transducers — but without using lead at all.
Microcatheter threads to travel through hair-thin arteries to deliver lifesaving treatments
The EPFL team created the MagFlow, which is an ultraminiaturized magnetic microcatheter that relies on the flow of blood to move forward, thus opening up the potential to treat conditions such as stroke, arteriovenous malformations and eye cancers in children.
Liquid metal framework heals bones while fighting infection
Future applications for the material could range from antimicrobial bone fillers and spinal fusion materials to 3D-printed scaffolds for cancer-related bone loss, diabetic foot and other high-risk infections, according to the Flinders' team.
New wearable patch enables battery-free, non-invasive skin cancer detection
The team determined that the patch clearly distinguished between healthy skin and potentially concerning spots, detecting unique electrical signals encountered with suspicious moles or lesions regardless of skin tone.
'Leaf' it to science: Faux foliage pummels pollution
The innovative device combines organic semiconductors with enzymes obtained from sulfate-reducing bacteria to break water down into hydrogen and oxygen or turn carbon dioxide into formate.
3D-printing approach could produce permanent dental crowns in just hours
The team suggests that the technique promises to transform crowns, bridges, veneers and other restorations by making them faster, more personalized and more convenient.
Fish blood could stop food and medicine from freezing
The mimic molecules promise to enable a wide variety of applications, from extending the shelf life of frozen foods to improving the storage and transport of life-saving biologics.
AI could help bad actors build bioweapons
The new study had a team of Microsoft scientists perform a hacker-style test to demonstrate that AI-generated sequences could potentially evade security software used by DNA manufacturers.
Scientists create matrix that functions like a fingerprint scanner to spot hidden objects
According to the researchers, the approach uses what they call a “fingerprint matrix,” which is a mathematical description of the way each object uniquely scatters waves such as light or ultrasound.
Next-gen bandage with AI technology expedites healing
The a-Heal system uses a tiny camera and artificial intelligence (AI) to detect each stage of healing and to deliver medication or treatment in the form of an electric field.
3D-printed tissue featuring fluid channels mimics real organs for surgical training
Researchers have developed a new 3D-printing method for creating realistic human tissue structures that could one day be used in the making of human models to train surgeons and doctors.
Smart glasses monitor health through blinking
The team believes that the device could potentially pave the way for assessing fatigue, mental workload and eye-related health issues in real-world settings, such as long-haul trucking or in the office.
Rethinking reach: Designing assistive exoskeletons for the upper limbs
Aging populations face rising rates of stroke and degenerative conditions requiring long-term rehabilitation, while industrial and service workers contend with fatigue and repetitive strain from overhead tasks. These demands highlight the need for technologies that extend physical capacity while preserving user autonomy.
