Following up on the success of cochlear and retinal prostheses, neuroscientists see a limitless horizon for related devices that will read electrical and chemical signals from the nervous system to improve quality of life for people suffering from injury or disease.

Such devices, neural prosthetics, will help a wide range of people, including people with epilepsy, wounded war veterans suffering post-traumatic stress disorder and traumatic brain injury, people with treatment-resistant depression and chronic pain, victims of Alzheimer's disease, people with speech disabilities, and individuals who have sustained spinal cord injury and loss of limbs.

But before neural prosthetics can advance, engineers will need to design and fabricate devices that can survive in the harsh environment of the human body, without causing tissue infection and other serious adverse conditions. In addition to enhancing materials performance, researchers are developing interface technologies that enable micro-devices to safely reside in human tissue for long time periods.

Researchers at the U.S. Department of Energy's Lawrence Livermore National Laboratory (LLNL) are making gains with thin-film flexible-polymer materials. In experiments with auditory prosthetics, neural interface micro-electrodes are embedded in polymer, allowing the device to move naturally and conform to live tissue. The polymer materials have mechanical properties that more closely mimic neural tissue than the micro wires used in current cochlear and deep-brain-stimulating implants.

"Among the engineering challenges associated with neural prosthetics is the biocompatibility of the implant," said Sarah Felix, a lead research engineer at LLNL and also a member of ASME. "Research suggests that polymer is more compatible with the human body than the silicon in conventional neural probes used in neuroscience studies."

Toward reliability

Researchers believe conventional, rigid, neural devices cause micro tearing in human tissue because neural tissue is softer than the device. According to Felix, the flexibility of a thin-film polymer probe mitigates this problem. However, the flexibility also makes polymer devices difficult to implant. Felix's solution is to temporarily attach a rigid stiffener.

"For the polymer neural interfaces, we attach the device to a needle-like stiffener using bio-dissolvable polyethylene glycol (PEG) to enable extraction of the stiffener after surgical insertion," said Felix. "An innovative bonding process enables accurate alignment of the device to the stiffener."

A novel feature of the design is a shallow channel running lengthwise, which allows the even distribution of the PEG, or other bio-adhesive, during assembly and implantation. Felix's team used the method to implant unique, dual-sided, polymer electrode arrays into brain tissue, and these arrays successfully recorded neural signals.

A promising future

The LLNL researchers believe their devices and surgical methods can also apply to future applications in deep-brain- and spinal-cord-stimulation, which will enable physicians to advance neural prosthetics to the next level of human health and rehabilitation. In fact, LLNL is currently developing neural implants that will restore auditory, motor and bladder function; aid speech; and control depression and epilepsy.

Each year, the U.S. National Institutes of Health (NIH) spends $6.5 million on neural prosthetics research and development, and today several of the most prestigious medical-research institutions in the United States — Case Western University and the Massachusetts Institute of Technology among them — are engaged in promising clinical studies.

Many medical scientists believe the sky is the limit for neural prosthetics, but ultimately it is the engineering community that will need to design and fabricate devices that enable the realization of the promise of neural modulation for patients.

Said Felix: "There exist many engineering considerations with neural prosthetics, particularly in the interface of the device with human tissue. Engineers must think about a complete range of issues, from electrode materials and the lifetime of the implant to electronics and signal processing. This will be an intriguing pathway of multidisciplinary scientific and engineering development for many years to come."

Soldering a LED to the 'Wrong' Side of a PCB

Why would you want to mount LEDs on the copper side of a single sided board?  How about if you want to mount a board directly behind a front panel with the LEDs showing through holes in the panel.  You can't put them on the usual side because the other components would stop the board fitting flush to the front panel, and you can't solder to the component side because there's no track there (unless you have a plated-through hole PCB).  I have just such a project in mind and this is the solution I came up with.

All you need is a couple of strands from a multi-strand cable; A power cable from a PC strips down nicely.  Put the LED in position and wrap a couple of turns of wire strand around one leg, pushing it down to the PCB with needle-nose pliers or a scalpel.  Feed one free end through the adjacent hole in line with the track and cut off the other end.  Solder the wrapped strand to the LED with a fine-tipped iron - See picture 3.

Turning the board over, hold the wire strand in place with a finger along the line of the track and solder as close as you can to the LED, being careful not to solder over the next hole along.  Cut off the loose end - See picture 4.   Repeat this and the previous step for the other leg and any other LEDs.

You now have LEDs mounted on the 'wrong' side of the board, and can continue adding the other components to the 'right' side.  Drill the front panel to accept the LEDs using a step drill and a scrap piece of matrix board as a measuring guide.  Before you position the board on a metal front panel, make sure that nothing from the PCB will short out.  Make a card spacer drilled the same as the front panel and put over the LEDs as an insulator before securing the PCB.

The final photos show the actual project build and how tightly you can pack LEDs with this method.  There's 7 x 5mm LEDs in a 3/4" (2cm) square which will have additional components filling the rest of the PCB and be mounted directly into an Altoids Smalls box lid.

Latest handmade Abaya trend

Abaya is a simple wear which is in the form of loose over garment. Abaya, also called as veil, is a rob-like dress which is worn in all the Islamic countries by the Muslims mostly. Latest handmade Abaya trend, defines a wide range of all the latest fashionable as well as simple Abaya styles and designs.

Traditional Abaya are long till the knees and are mostly found and stitched in black color. It is also choice of a customer that she can opt for this in any color. Different Sizes are also available like small medium and large. Some of the ladies purchase the ready-made Abaya and some of them find themselves comfortable, in getting the unstitched cloth. Then this unstitched cloth is being stitched in different styles. Abaya is found with a veil or a cover stole too. This cover stole is used to cover up the face as Muslim females cover their faces for the sake of pardah. Some of the females just take stole to cover up their head and hair. It is used in both of the cases.
