مقاله علمی: Global cortical activity predicts shape of hand during grasping

Recent studies show that the amplitude of cortical field potentials is modulated in the time domain by grasping kinematics. However, it is unknown if these low frequency modulations persist and contain enough information to decode grasp kinematics in macro-scale activity measured at the scalp via electroencephalography (EEG). Further, it is unclearl as to whether joint angle velocities or movement synergies are the optimal kinematics spaces to decode. In this offline decoding study,…

Power vest CareJack

Research News  Mar 02, 2015 Each year millions of people within the EU injure themselves in the course of their work due to picking up heavy loads or from one-sided movements – ending up with serious health issues. Together with the industry, Fraunhofer researchers are developing a vest designed to take the burden off caregivers and others with physically demanding jobs. read more

Grasshopper Suit

The Florida Institute for Human and Machine Cognition has developed a novel exoskeleton designed to stop muscle and bone density loss caused by long stays in a zero gravity environment. Known as the Grasshopper, the suit would be worn by astronauts while they exercise in space. It’s worn much like a hiking backpack — over the shoulders and around the waist. But it also includes foot plates with straps that go over the user’s shoes. The…

پنج سکوی سخت افزاری برای انجام محاسبات فیزیولوژیک

Physiological computing focuses on the use of biosignals for the development of interactive software and hardware systems capable of sensing, processing, reacting, and interfacing the digital and analog worlds. However, biosignals have specific requirements for which typical physical computing platforms are not particularly tuned. Until recently, many projects ended up hindered by high costs and limited access to suitable hardware materials. That scenario is different today, partially thanks to the following 5…

Researchers Build Brain-Machine Interface to Control Prosthetic Hand8

March 31, 2015 A research team from the University of Houston has created an algorithm that allowed a man to grasp a bottle and other objects with a prosthetic hand, powered only by his thoughts.   The technique, demonstrated with a 56-year-old man whose right hand had been amputated, uses non-invasive brain monitoring, capturing brain activity to determine what parts of the brain are involved in grasping an object. With that information,…

e-NABLE foundation: A Global Network Of Passionate Volunteers Using 3D Printing To Give The World A “Helping Hand

When the e-NABLE community first began in 2013, it consisted of about 300 people who owned 3D printers or who had design skills to share – that wanted to help improve the first open sourced design for 3d printed hands that had been released online. They simply wanted to use their machines to help to print and assemble free 3D printed prosthetic devices to anyone that reached out to them.A year and…

Bionic Boots

Initially, the concept was to emulate and experience the sensation and speed of running like a fast animal. I still have the same goal, but the invention is evolving through the use of future technologies to reach new endeavors. I want to produce a viable form of environmentally sound transportation over any terrain, be it city streets or off-road trails — and to run faster than any man alive. The first spark…

The Very Real Future of Iron Man Suits for the Navy

The Very Real Future of Iron Man Suits for the Navy One day, troops will strap on bulletproof Iron Man suits and fly into battle, but only after a breakthrough in portable power storage that may not arrive for another decade. In the meantime, exoskeletons do have real military potential today, if only the Pentagon can shed some of its comic-book inspired notions and deploy them where they can do the most good…
