March of the microscopic robots

Building robots at the micron scale is tricky, particularly when it comes to designing small-scale ‘actuators’ – the motors that allow robots to move. Conventional actuators don’t work at such a small scale, and new actuators that do work use mechanisms like magnetism and are difficult to integrate with traditional silicon based micro-electronics. Now a […]

Synchron Stentrode: Brain Computer Interface for Paralysis

The first endovascular neural interface, the Stentrode™ is a minimally invasive implantable brain device that can interpret signals from the brain for patients with paralysis. Implanted via the jugular vein, the #Stentrode is placed inside the #brain in the command-control center, known as the motor cortex, but without the need for open brain surgery. The […]

Cell-like nanorobots: interview with UC San Diego nanoengineers

Engineers at the University of California San Diego have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria and the toxins they produce. Berta Esteban-Fernández de Ávila and Professor Joseph Wang from the Department of NanoEngineering at UC San Diego describe the project in this video.

Brain Machine Interface — Katie Gant, Ph.D.

Katie Gant, Ph.D., a researcher at The Miami Project to Cure Paralysis and Department of Biomedical Engineering, works with a research subject to develop a neuroprosthetic brain-machine interface. Electrical signals generated in the person’s brain are measured by a wireless EEG headset and sent to a computer, where signals are decoded in real-time. Electrical stimulation […]

The World's Smallest Robots: Rise of the Nanomachines

This week Reactions takes a look at some byte-size science. Nanomachines have some very tiny chemistry at play with some big results. Nanomachines – including nano-sized motors, rockets and even cars – are many orders of magnitude smaller than a human cell, but they have huge promise. In the future, they could deliver drugs anywhere […]
