Devices for the Future

Device Description

Brain controlled prosthetics that have been designed so well that they are almost natural, are the focus of this paper. These limbs enabled humans to figure out how to move them in similar ways as they would coordinate their own arm movements, and consequently get the prosthetics arms to actual functionality (Collinger, B. Wodlinger, Wang, Tyler-Kabara, & Weber, 2013). The research method constituted decoding and recording of motor cortical signals so as to present the participants in the research with the ability to coordinate approximately 10 DOFs with the prosthetic systems of the arm.

The Development Process

Micro-electrode arrays for capturing brain signals on record and establishing complex algorithms to decode natural processes and transforming them into commands for motors in prosthetic systems of the arm are set in process. Single element neural signals have been captured in human clinical patients by implanting a pair of intra-cortical arrays; microelectrodes (Blackrock Microsystems, Salt Lake City, UT) that constituted 96 electrode shanks. The 4x4 millimeter compositions were put in the motor cortex (MI) of the participants and lined percutaneously by use of a pair of head-mounted pedestals. By utilizing some preoperative functional and structural MRI and MEG to mark finger and hand activation places in M1 with the intention of deciphering grasp behavior, the arrays were inserted at 14 mm from each other by use of stereotaxic surgical navigation technology method (Collinger, et al., 2014). The collective signals from the arrays facilitated for the synchronized recording of above 250 single units that were unique, and consequently processed immediately to eventually send signals to move the APL/JHU prosthetic limb.

Potential Markets, the Need for the Limbs and who Benefits

The aim of this project was to assist improve the quality of life of amputees from war. It was also to enhance their independence and functioning, to enable daily living activities and resuming service. DARPA started working on this project as a response to a high number of amputees and nervous system injuries that were recorded among members of the service. Significant upper extremity injuries and disabilities are a marked issue in the Department of Defense. Statistical data shows that there was approximately 6000 amputation of service members in the U.S. armed forces; cases between the years 2011. Two thirds of these amputations were those of the upper extremities (O'Donnell, 2012). Apart from amputees, the prosthetics in this revolutionary project is of great help to people who have suffered the loss of functionality of the upper extremity, because of an injury of the spinal cord. Further data shows that the U.S. alone has about 300,000 people with SCI. There are 12,000 cases added each year.

Where the Prosthetic Limb is Made

This miracle Device can be got from The Johns Hopkins University Applied Physics Laboratory (JHU/APL) and DEKA. They took up the challenge to design and build the device to fulfill the demands of the program (Robbin, et al., 2015).

Estimate Cost

A BCI system that is non-invasive costs approximately $10,000, plus the cost of the fees for extra-technical support.
