Exoskeleton Helps Amputees to ‘Power Walk’

Engineers are developing a lightweight, motorized exoskeleton that can restore much of the sensation of walking with two healthy legs. The goal is to provide that extra energy so walking feels natural again. The device features a lightweight, efficient electromechanical actuator connected to the user’s thigh above the amputation.

Ultrasound Enables ‘Deep-Brain’ Treatment, Without the Implant

A treatment known as deep-brain stimulation requires the implantation of a surgical device to treat neurological disorders like Parkinson’s disease and epilepsy. A team has developed a new method of brain stimulation that does not call for an implant. Instead, the team uses focused ultrasound to turn specific types of neurons in the brain on and off, enabling precise control of motor activity without surgical device implantation.

Armband Device to Predict Gestures and Control Prosthetic Hands

Researchers have developed a device that combines wearable biosensors with AI software to help recognize what hand gesture a person intends to make based on electrical signal patterns in the forearm. The device paves the way for better prosthetic control and more seamless interaction with electronic devices. The flexible armband design can read the electrical signals at 64 different points on the forearm.

‘DeepDOF’ AI Microscope Could Confirm Tumor Removal in Minutes

When surgeons remove cancer, one of the first questions is whether all the cancerous tissue was removed. A new microscope can quickly image large tissue sections, even during surgery, to find the answer. The deep learning extended depth-of-field microscope (DeepDOF) utilizes the AI technique of deep learning to train a computer algorithm to optimize both image collection and image post-processing.
