Neuroscientist Demonstrates How One Person’s Brain Can Control Another Person’s Arm

Neuroscientist Greg Gage demonstrates how one person’s brain can be used to control another person’s arm. Gage uses cheap equipment to read the nerve impulses from his one person. He then can relay those impulses through a “human-to-human interface” into the arm of another person. Once the setup is properly configured, whenever the first person moves her hand it causes the other hand to move involuntarily. The video demonstrates the interface in detail, including construction info for the device.

And this is his recent TED Talk:

Smart Phone Guided Pedestrians

German scientists are experimenting with the use of an app to guide the walking of a pedestrian. Of course EMS on the skin’s surface doesn’t have the ability to fully control most leg muscles, so they are only using the stimulation as a suggestion for the user to walk in that direction.

Second Spine

Second Spine

These researchers created second spine, an upper body assistive device for human load carriage. They wanted to reduce musculoskeletal injuries caused due to carrying heavy loads. What they designed was a wearable upper body device that can prevent musculoskeletal injuries during human load carriage by providing a secondary load pathway to transfer the loads from shoulders to pelvis while also allowing a good range of torso motion to the wearer. Loads were transferred through segmented columns between the shoulder support and hip belt. The design had had two primary considerations: load distribution between shoulders and pelvis, and preserving the range of torso motion. A further iteration compensates for inertial forces by real-time sensing of human motion and actuation of the motors in a way that the backpack motion is kept nearly inertially fixed.
