Starting next year, Honda will begin fitting vehicles with a new, advanced-design passenger-side front airbag that its engineers said is designed to mitigate brain and neck injuries by cradling the head like a baseball in a catcher's mitt. The design is particularly effective, Honda said, for angled impacts or when an occupant is not in optimal position when the crash occurs, reducing rotational acceleration of the head that can traumatize the brain.

Less Training Needed for Brain-Machine Interfaces

  • Magazine Article
  • TBMG-35338
Published 2019-10-01 by Tech Briefs Media Group in United States

Brain-machine interfaces (BMIs) are rarely found outside of medical clinics, where the disabled receive hours or days of training in order to operate wheelchairs with their minds. Now the largest-ever BMI experiment Mental Work, conducted as an experimental artwork at EPFL's Artlab, has provided preliminary evidence that training time can be shortened, the use of dry electrodes are a robust solution for public BMI and that user performance tends to improve within a relatively short period of time.

Smart Brain Stimulators: Next-Generation Parkinson's Disease Therapy

Published 2019-10-01 by Tech Briefs Media Group in United States

Researchers at the University of Houston have found neuro biomarkers for Parkinson's disease that can help create the next generation of “smart” deep brain stimulators, able to respond to specific needs of Parkinson's disease patients. Those with the disease often undergo the high-frequency brain stimulation, a well-established therapy for the progressive nervous system disorder that affects movement, but the therapy has been imprecise.

New Optical Endoscopy Using Ultrasound Could Replace Scopes

One day, scopes may no longer need to be inserted into the body — such as down the throat or under the skin — to reach the stomach, brain, or any other organs for examination.

Magnetic Metamaterial Amplifies MRI

  • Magazine Article
  • TBMG-35120
Published 2019-09-01 by Tech Briefs Media Group in United States

Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create images of organs and tissues in the human body, helping doctors diagnose potential problems or diseases. Doctors use MRI to identify abnormalities or diseases in vital organs as well as many other types of body tissue, including the spinal cord and joints.

Senior Virtual Assistant Mitigates Impact of Dementia and Delirium

  • Magazine Article
  • TBMG-35090
Published 2019-09-01 by Tech Briefs Media Group in United States

An estimated 50 million people worldwide are living with dementia, resulting in more than $1 trillion each year in healthcare costs. Artificial emotional intelligence (AEI) technology developer BPU Holdings has been researching methods to reduce the complications associated with the disease. Its senior virtual assistant (SeVA) technology utilizes computer-simulated emotion to provide a new level of support for dementia patients to mitigate their pain. In doing so, the technology is expected to reduce treatment costs in the millions of dollars globally.

Incompressibility of the brain makes it susceptible to damage from shear strains. Head rotational motion can easily produce high shear strains causing brain injury. Since head injury criterion (HIC) does not account for rotational motion, a brain injury criterion (BrIC) was developed. To design potential countermeasures for reducing BrIC, it is important to investigate the parameters that influence BrIC. This article focuses on parametric analysis to examine the sensitivity of BrIC to vehicle design and crash-related parameters, and identifying important parameters which can be controlled in developing countermeasures for reducing BrIC. Global Human Body Models Consortium (GHBMC) 50th percentile male simplified human finite element (FE) model was used in this study. Four different analyses were conducted: a Design of Experiments (DOE) study to investigate sensitivity of BrIC to impact direction and crash pulse severity b DOE studies, with fixed crash severity, for frontal, far side oblique, and near side oblique crash modes to identify important vehicle design parameters influencing BrIC c Optimization for frontal, far side oblique, and near side oblique crash modes to minimize…

Published 2019-08-01 by Tech Briefs Media Group in United States

In 2016, UC Berkeley engineers demonstrated the first implanted, ultrasonic, neural dust sensors. Now, taking the next step, the smallest-volume wireless nerve stimulator was developed, called StimDust (stimulating neural dust).

Wearable System to Sense and Stimulate the Brain

Published 2019-08-01 by Tech Briefs Media Group in United States

A team of researchers from Carnegie Mellon University is starting a project to design and implement a noninvasive neural interface that can be used as a wearable device. This neural interface will be capable of both recording and stimulating the brain's dynamic activity with high temporal and spatial resolution.

Graphene Monolayer Improves Implantable Neurostim Devices

  • TBMG-34983
Published 2019-08-01 by Tech Briefs Media Group in United States

One of the most commonly used elements in neurostimulation devices is platinum microelectrodes, but they are prone to corrosion, which can reduce the functional lifetime of the devices. Researchers have come up with a solution to help: adding a graphene monolayer to the devices to protect the microelectrodes. The graphene monolayer is an effective diffusion barrier and electrical conductor.
