Plant-Based Soft Medical Robots

Researchers at the University of Waterloo in Canada have developed plant-based microrobots that are intended to pave the way for medical robots that can enter the body and perform tasks, such as obtaining a biopsy or performing a surgical procedure. The robots consist of a hydrogel material that is biocompatible and the composite contains cellulose (Read more...)

Stretchable E-Skin for Robotic Prostheses

Engineers at the University of British Columbia have collaborated with the Japanese automotive company Honda to develop an e-skin for robotic prostheses that allows such devices to sense their environment in significant detail. The soft skin is highly sensitive, letting robotic hands to perform tasks that require a significant degree of dexterity a (Read more...)

Phone Attachment for Pupil Measurements with Any Skin Tone

A research team at the University of California San Diego have developed a smartphone attachment that can provide information on changes in pupil size, which can be used to assess neurological phenomena, such as traumatic brain injury and Alzheimer’s disease. Such changes in pupil size have been difficult to characterize in the past in those […]

Glasses Provide Audible Prompts for Blind Wearers

A team at the University of Technology Sydney has developed an assistive technology for blind people and those with low vision. The system consists of glasses that can view their surroundings through an on-board camera, appraise the objects nearby using computer vision technology, and then play a sound that provides a cue for the wearer […]

Magnetic Dressing Improves Diabetic Wound Healing

Researchers at the National University of Singapore have developed a magneto-responsive hydrogel wound dressing that also contains two different regenerative cell types. The hydrogel is also embedded with magnetic particles that can be stimulated using an external magnetic field. The action of the magnetic field on the gel-encapsulated particles ca (Read more...)

A Wearable to Manage Parkinson’s Motor Symptoms: Interview with Lucy Jung, CEO at Charco Neurotech

Charco Neurotech, a medtech company based in the United Kingdom, has developed CUE1, a non-invasive wearable that is intended to assist those with Parkinson’s disease to manage their motor symptoms. The device is typically affixed to the sternum, and provides vibratory action in a focused region of the body. The technology is based on the […]

Robotic Ankle Helps with Postural Control in Amputees

Researchers at North Carolina State University have developed a robotic prosthetic ankle that can provide stability for lower limb amputees. The ankle uses electromyographic sensors placed on the sites of muscles in the residual limb that then convey the intentions of the wearer with regard to movement. So far, the system has been shown to […]

Lung Chip Mimics Radiation Injury

Researchers at the Wyss Institute at Harvard University have developed a microfluidic chip that can recreate some of the features of radiation-induced lung injury. The lungs are very sensitive to radiation, and this can limit the application of radiotherapy to treat cancer. Accurately modeling radiation-induced lung injury could assist in developin (Read more...)

Eko’s Newest CORE 500 Stethoscope: A Review

Arriving in two boxes reminiscent of Apple product packaging – one for the chest piece (the part that contacts the body), and another for the detachable earpiece (tubes + ear tips) – the CORE 500 is clearly an upgrade from the Eko DUO stethoscope. Similar to its predecessor, the CORE 500 can be used with […]

Bacteria Tag Team Tumors with T Cells

A team at Columbia University School of Engineering and Applied Science has developed a technique to enhance chimeric antigen receptor (CAR) T cell therapy in solid tumors. The technique involves engineering E. coli bacteria, that naturally tend to accumulate in the immune privileged core of solid tumors. The bacteria have been engineered to intera (Read more...)

Device Vibrates DNA for Highly Sensitive Detection

Researchers at the University of Massachusetts Amherst have developed a new method of detecting very small amounts of DNA. The breakthrough could allow clinicians to spot genetic markers of disease at the point-of-care, as the approach does not require conventional laboratory analysis, which is usually time-consuming and costly. In fact, the approa (Read more...)

Suction Cup Delivers Drugs Through Cheek

Researchers at ETH Zurich in Switzerland have developed an alternative to injections as a way to deliver large drugs, such as peptides, minimally invasively into the blood stream. The suction cup created by these researchers is inspired by octopus suckers, and it affixes to the mucosal lining of the inside of the cheek. The cup […]

Enhanced mRNA Vaccine May Work Intranasally.

Researchers at MIT have developed an enhanced mRNA vaccine system that can elicit a greater immune response at lower doses. The vaccine technology is so potent that it may be useful for intranasal COVID-19 vaccines. This would have the benefit of localized immunity in the nasal mucus membranes that could kill the SARS-CoV-2 virus before […]

Lateral Flow Test for Gingivitis

Researchers at the University of Cincinnati have developed a lateral flow assay that can detect bacterial toxins from Porphyromonas gingivalis, the causative bacteria for gingivitis. The technology could make it easier and faster to identify early-stage gingivitis, which can lead to periodontitis and eventual tooth loss, as well as contributing to (Read more...)

Sensor Monitors Transplanted Organs for Signs of Rejection

Researchers at Northwestern University have developed a sensor that can monitor transplanted organs for signs of rejection. Patients who receive transplants require immunosuppressive medication to ensure that their body does not reject the transplanted tissue, but this can still happen, sometimes years after the initial transplant. Current methods (Read more...)

miRNA Therapy Slows Cancer Growth

Scientists at Purdue University have developed a microRNA therapy designed to slow tumor growth. The technology takes advantage of the tendency of several cancer types to express an excess of surface receptors that bind folate (vitamin B9) and draw it into the cell interior. By attaching the microRNA strand to a folate molecule, the researchers […]
