Smart Bandage to Monitor and Deliver Targeted Treatment for Chronic Wounds

Caltech researchers have developed a new type of smart bandage that uses a custom-developed electrochemical biosensor array to treat chronic wounds, such as diabetic ulcers and burns. The bandage is made of a flexible polymer containing embedded electronics and medication that can monitor molecules, pH levels, and temperature in the wound. The wearable patch is…
Researchers Develop Stretchable Sensor to Monitor Muscle Atrophy

Researchers at The Ohio State University have developed the first wearable sensor to detect and monitor muscle atrophy. The sensor uses stretchable conductive threads in a zig-zag pattern, allowing it to fit various limb sizes. This device could offer an alternative to MRI monitoring. Simulation and in vitro results show good agreement, with the sensor…
Cloud-Based System Using AI and Radio Waves to Monitor Elderly Health

Researchers at the University of Waterloo have developed a cloud-based system for non-contact, real-time monitoring of elderly people’s health in their living spaces without wearable devices. The system employs low-power millimeter-wave radio systems and AI to track individuals’ activities continuously and accurately, alerting healthcare workers to potential health issues or sudden falls. The technology can…
Implantable Multifunctional Sensor using Ultrasoft Hydrogel for Monitoring Overactive Bladder

Researchers from POSTECH and Korea Advanced Institute of Science and Technology (KAIST) have developed a highly stretchable and tissue-adhesive multifunctional sensor that can monitor bladder activity in overactive bladder (OAB). The researchers have developed a sensor to monitor the bladder’s mechanical and bioelectrical activities in real-time. The sensor is based on structurally engineered islets embedded…
Real-Life Gait Analysis for Using Millimeter-Wave Radar

Researchers at Chalmers University of Technology in Sweden have developed a method for predicting fall accidents and cognitive illnesses such as Alzheimer’s disease by reading a person’s walking pattern with a radar sensor. It involves the use of a millimeter-wave radar to monitor walking steps in real-life environments for the elderly, with the aim of…
Blood-vessel-on-chip to study vascular malformations caused by PIK3CA mutations

Researchers at the University of North Carolina have created a model that mimics vascular malformations (VMs) that are specifically caused by a mutation of PIK3CA. The researchers created a microfluidic model of these VMs using human cells that have the mutated gene. They found that the abnormal blood vessels in their model closely resemble the…
Researchers develop new method to improve bioprinting resolution with Iodixanol

Researchers at the University of California San Diego have made advances in bioprinting 3D-engineered tissues. Bioprinting is a process of creating biological structures and tissues using cells and biopolymer. This study describes a type of bioprinting called digital light processing (DLP). Current bioprinting techniques have challenges in achieving key requirements of high cell density, high…
Predicting newborn health outcomes with electronic health records data

Researchers used electronic health records (EHRs) and advanced machine learning methodologies to predict neonatal outcomes from maternal conditions. The study used data from 32,354 mother-newborn dyads to train and validate the model and found it outperformed currently used EHR-based clinical risk scores. The study identified previously unreported associations between maternal conditions, such as anemia, certain…
AI-powered smart prosthetic socket for thigh amputees

The Korea Institute of Machinery and Materials (KIMM) has developed an innovative, customizable prosthetic socket that automatically fills the socket with air upon detecting the empty space inside of the socket in real time based on artificial intelligence. The socket includes an inflatable air bladder that monitors pressure and maintains uniform pressure distribution while walking.…
Researchers develop self-charging air filter-based mask with prolonged electrostatic adsorption efficacy

Researchers from the City University of Hong Kong have developed a self-charging electrostatic face mask that can continuously replenish its electrostatic charge and maintain high filtering performance for up to 60 hours without needing external power sources. The mask, which uses the triboelectric effect between the electrospun poly(vinylidene fluoride) nanofiber film and nylon fabric, and…
