Soft Robotic Exosuit for Stroke Survivors

To allow stroke patients to recover, many rehabilitation centers have looked to robotic exoskeletons. But although there are now a range of exciting devices that are enabling people to walk again who initially were utterly unable to do so, there remains significant active research trying to understand how to best apply wearable robotics for rehabilitation after stroke.

Smart Bandages to Heal Chronic Wounds

Chronic and non-healing wounds—one of the most devastating complications of diabetes and the leading cause of limb amputation—affects millions each year. Due to the complex nature of these wounds, proper clinical treatment has been limited.

Printing Objects That Can Incorporate Living Organisms

A method for printing 3D objects that can control living organisms in predictable ways has been developed. The technique may lead to 3D printing of biomedical tools, such as customized braces, that incorporate living cells to produce therapeutic compunds such as painkillers or topical treatments, the researchers say.

Exosuit shows potential for wearable robots

Researchers have previously developed robotic devices for rehabilitation and other areas of life that can either assist walking or running, but no untethered portable device could efficiently do both.

Noninvasive neuromodulation to treat obesity

Novel approaches that have been tested to treat obesity include noninvasive neuromodulation techniques such as transcranial direct current stimulation. Studies performed to date have suggested that this method does in fact help reduce appetite, food intake and body weight, but only in some subjects.

Using AI to predict breast cancer and personalize care

Researchers have created a new deep-learning model that can predict from a mammogram if a patient is likely to develop breast cancer as much as five years in the future. Trained on mammograms and known outcomes from over 60,000 MGH patients, the model learned the subtle patterns in breast tissue that are precursors to malignant tumors.

A safe, wearable soft sensor

Children born prematurely often develop neuromotor and cognitive developmental disabilities. The best way to reduce the impacts of those disabilities is to catch them early through a series of cognitive and motor tests. But accurately measuring and recording the motor functions of small children is tricky.

Robots with sticky feet

Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take over a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart, adding time and costs to maintenance. This problem is not only confined to jet engines, either; many complicated, expensive machines.

Predicting leaky heart valves with 3D printing

Researchers have created a novel 3D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient's unique anatomy, before the medical procedure is actually performed.

Electrical stimulation in the nose induces sense of smell

Physicians have, for the first time, induced a sense of smell in humans by using electrodes in the nose to stimulate nerves in the olfactory bulb, a structure in the brain where smell information from the nose is processed and sent to deeper regions of brain.

Gentle robotic hand for sea life

The open ocean is the largest and least explored environment on Earth, estimated to hold up to a million species that have yet to be described. However, many of those organisms are soft-bodied - like jellyfish, squid, and octopuses - and are difficult to capture for study with existing underwater tools, which all too frequently damage or destroy them. Now, a new device safely traps delicate sea creatures inside a folding polyhedral enclosure and lets them go without harm using a novel, origami-inspired design.
