Scientists at Penn State University developed a wearable glucose monitor that can non-invasively measure glucose levels within sweat in real time. The low-cost sensor consists of laser-induced graphene and a nickel-gold alloy that can detect the very low levels of glucose in sweat without the use of enzymes. The sensor contains a microfluidic chamber into which sweat is drawn, and then an alkaline solution reacts with the glucose in the sweat, causing a reaction in the alloy and a substantial electrical signal. Measuring glucose levels is a pain, literally. From...

AdhereTech, a medtech company based in New York City, has developed the Aidia Smart Bottle (previously known as the Smart Pill Bottle), a connected pill bottle that helps to increase medication compliance using lights, audio alerts, and text message reminders. The bottle will remind patients to take their medication and remind them if they have missed a dose. Poor medication compliance can be the decider between disease management and disease progression. During the COVID-19 pandemic many patients with chronic health conditions were not in regular contact with their physicians and...Read More

Researchers at the University of Utah built an exoskeleton that can ease walking for people with above-knee amputations. The new system, which uses an electromechanical actuator attached to the thigh and AI to adapt to each person’s walking style, significantly reduces energy consumption for users. Above-knee amputations are particularly challenging in terms of walking. Many of the leg muscles are removed, meaning that the remaining muscles, both residual and intact, have a lot of work to do. Conventional prosthetic legs do not provide any assistance while walking, so users have...Read More

As cloud and digital platforms continue to gain traction, we’re seeing a trend toward increased investments in robotic surgery in medical technology fields. Surgical training, coordination, and collaboration in the operating room are areas where digital tools can help shorten learning curves. While robotic technology continues to transform healthcare worldwide by allowing surgeons to perform cases with increased precision and decreasing patient downtime, use of surgical robotics does have an increased learning curve and time required for mastery. This is where many companies have begun to make a difference in...Read More

Telemedicine
Researchers at the Technical University of Munich in Germany have developed a telemedicine system for high-risk COVID-19 patients who are isolating at home. The system consists of an ear sensor that monitors a variety of physiological parameters, including heart rate, respiration, oxygen saturation, and body temperature. The project also involves clinicians calling the patient daily to check in with them. Patients may not realize that their condition is deteriorating until it is too late, and the telemedicine system aims to alert clinicians ahead of time, allowing them to intervene early....Read More

Luminopia, a company based in Cambridge, MA, has developed Luminopia One, a visual content system that aims to treat amblyopia, also known as ‘lazy eye,’ in young children. The condition is caused by neurological deficits that typically affect vision in one eye. At present, the condition is treated using corrective glasses, eye patches, or eye drops, none of which young children are big fans of. The Luminopia One system is different, and involves kids wearing a standard virtual reality (VR) headset, through which they watch TV shows or movies for...Read More

At the University of Arizona a team of engineers have developed 3D-printed wearable devices that are custom made for each user. The personalized fit means that they do not require adhesives to stay in place. The technology can be used to monitor a variety of physiological parameters, including body temperature and muscle deformation during physical activity. Strikingly, the new devices do not require a battery, and instead use far-field energy harvesting to wirelessly obtain power from another nearby device, while communicating with a smartphone using Bluetooth. Wearables promise a new...Read More

A collaboration between groups at MIT and Dana-Farber Cancer Institute led to the creation of a system that allows for quick determination of the susceptibility of cancer cells to specific drugs, without the need to rely on genomic markers. The technique consists of flowing the cells through vibrating microchannels, which lets the researchers obtain single cell mass measurements in a high-throughput manner. By comparing the weights of cells that have been treated with a drug to those of untreated cells, the researchers can quickly identify whether a drug will have...Read More

At the University of Bern in Switzerland, researchers have developed the Panoramic Opto-Electrical Measurement and Stimulation (POEMS) system, which allows them to conduct advanced optogenetic experiments with mouse hearts. The device, which contains a volume into which a mouse heart can be placed, lets the Swiss team stimulate various cell types using light, and then measure the resulting electrical response. Previously, scientists had no way to track electrical activity and provide accurate optical stimulation at the same time. The new technology may help to determine the contribution of various cell...Read More

A team of scientists at University of California Los Angeles created a magnetoelastic device that can generate electricity from movements of the body, including the movements caused by the pulse at the wrist. The patch-like device may help to power medical wearables or implantable sensors, and may function as a waterproof heart rate monitor in its own right. The technology is based on the magnetoelastic effect, in which small magnets within the material move closer and farther away from each other as the material flexes. This causes the strength of...Read More

Evolution Devices, a company based in California, created a functional electrical stimulation device to assist people with foot drop to walk more freely. Foot drop is caused by muscle weakness/paralysis, and those affected struggle to lift the front part of their foot, which makes walking difficult and can lead to falls. The product is called EvoWalk, and it consists of an electrical stimulation device that stimulates muscles in the leg that can lift the foot at exactly the right time during walking. The device gathers data on patient activity which...Read More

Scientists at Ecole Polytechnique Fédérale de Lausanne in Switzerland created a wireless photoelectric implant that allows them to activate or suppress certain neurons in the mouse spinal cord. The flexible implant is controlled through Bluetooth and contains miniaturized LEDs that emit red light, which helps to avoid absorption and reflection by nearby neurons. The researchers hope that the technique could allow for more advanced optogenetics studies, and even pave the way for clinical implants to treat patients with neurological disorders. Optogenetics is an advanced technique that allows researchers to delve...Read More
