Personalized Healthcare Calls for Innovative Wearables and Medical Devices

Because the world population is aging, chronic diseases are on the rise and healthcare costs are reaching unsustainable heights, it is essential to detect pathologies early. The Internet of Things (IoT) is now poised to transform the healthcare industry by providing wireless connectivity and sensing. Body-worn electronics and implanted devices, equipped with tiny sensors that continuously monitor vital parameters and securely report anomalies to appropriate physicians, will improve patients’ quality of life while delivering timely medical help. Personalized healthcare is making medicine participatory, personalized, predictive and preventive (P4 Medicine). Medical device and high-tech companies are joining forces to satisfy a growing demand that might reach 20 billion medical connected devices by 2020. Successful medical device and pharmaceutical companies are using engineering simulation to develop systems that ensure high reliability, provide data privacy and achieve regulatory compliance quickly. Learn how platform-based engineering simulation maximizes the IoT opportunities for personalized medicine.

How the Automotive and Ground Transportation Industry is Accelerating with Pervasive Engineering Simulation

Consumers are demanding efficient, reliable, safe, environmentally friendly, smarter, connected and increasingly autonomous vehicles. Regulators continue to demand improvements in safety and emissions. The automotive industry must deliver these increasingly complex products to market faster, in the face of increasing competition from traditional sources, new geographies and new entrants and with continued pressure to reduce cost. Failure of any magnitude can result in significant, and even irreparable, financial and brand impact.

The 3D Printing Landscape: Then and Now

Frequently used as a design validation and prototyping tool in its early days, the 3D printer now supports a much wider range of applications, from shape-conforming electronics to the creation of printed living tissue. Tech Briefs spoke with industry expert Terry Wohlers about 3D printing's emerging possibilities.

Electric Patch Holds Promise for Treating PTSD

An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study — survivors of rape, car accidents, domestic abuse and other traumas — an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.

Blast-Induced Acceleration in a Shock Tube

High-fidelity simulation of blast flow conditions can aid in developing strategies to mitigate blast-induced brain injury.

Army Medical Research and Materiel Command, Fort Detrick, Maryland

The prevalence of blast-induced traumatic brain injury (bTBI) has prompted an urgent need to develop improved mitigation strategies and advance medical care targeting casualties with bTBI. Despite considerable effort, the basic mechanisms of blast-induced brain injury are still undefined. Based largely upon computational modeling, several candidate mechanisms of nonimpact bTBI have been identified and include head acceleration. This work hypothesizes that explosion flow conditions can cause head acceleration sufficient to injure the brain, and that these inertial forces combine with other injury mechanisms to yield bTBI.

Wireless Sensor Enables Study of Traumatic Brain Injuries

A new system that uses a wireless implant has been shown to record – for the first time – how brain tissue deforms when subjected to the kind of shock that causes blast-induced trauma commonly seen in combat veterans.

MIT Provides Yeast a Different Environment for Ethanol Tolerance

Ethanol and other alcohols can disrupt yeast cell membranes, eventually killing the cells. In research funded by the MIT Energy Initiative and the U.S. Department of Energy, researchers at MIT and the Whitehead Institute for Biomedical Research found that adding potassium and hydroxide ions to the medium in which yeast grow can help cells compensate for that membrane damage.

Wireless Vital Signs Monitor for Trauma Patients

This monitor enables users to triage, prioritize transport, and track changes in numerous casualties from a remote location.

A miniature, portable wireless vital signs monitor (MWVSM), called Mini-medic™, could aid in the triage and diagnosis of trauma patients with and without traumatic brain injury (TBI). The MWVSM consists of two components, both of which are the approximate size and weight of a cellphone: one is a sensor that is placed either on the forehead or the fingertip of a patient, and the other is a monitor that receives a wireless signal transmitted up to 100 m carried by the medic.

Effect of Acceleration Frequency on Spatial Orientation Mechanisms

This technology could help desensitize individuals to motion sickness caused by aircraft, vehicle, and ship movements.

Extreme motion environments can induce loss of visual acuity, motion sickness, and spatial disorientation. Understanding how human sensory integration of acceleration stimuli affects spatial awareness will improve models of spatial disorientation and mishap analysis. While there are numerous studies describing vestibular semicircular canal responses to angular acceleration, less is known about vestibular otolith responses to linear acceleration. This gap in knowledge is important to resolve, since seasickness and airsickness are highly dependent on the predominant frequency of a linear acceleration stimulus.
