STANFORD ENGINEERS CREATE ARTIFICIAL SKIN THAT CAN SEND PRESSURE SENSATION TO BRAIN CELL

Stanford engineers have created a plastic skin-like material that can detect pressure and deliver a Morse code-like signal directly to a living brain cell. The work takes a big step toward adding a sense of touch to prosthetic limbs.

Stanford chemical engineering Professor Zhenan Bao and her team have created a skin-like material that can tell the difference between a soft touch and a firm handshake. The device on the golden "fingertip" is the skin-like sensor developed by Stanford engineers. (Bao Lab) Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell.

MOST SENSORS DESIGNED TO MEASURE HEAD IMPACTS IN SPORTS PRODUCE INACCURATE DATA, STANFORD BIOENGINEERS FIND

As scientists zero in on the skull motions that can cause concussions, David Camarillo's lab has found that many commercially available sensors worn by athletes to gather this data are prone to significant error.

Amid growing concern about sports-related concussions, some athletes are beginning to wear head-mounted sensors that gauge the speed and force of impacts they receive during competition. Scientists are still working on identifying baseline parameters for injury, but research suggests that certain skull motions can contribute to concussions, and constant in-game monitoring of those motions promises to help limit injuries.

Stanford engineers' new manufacturing process could yield better solar cells, faster chips.

Silicon isn't the only chip-making material under the sun, just the cheapest. But a new process could make the alternative material, gallium arsenide, more cost effective.

Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material, and it has certain technical advantages over silicon - electrons race through its crystalline structure faster than they can move through silicon.

Wrinkle predictions.

New mathematical theory may explain patterns in fingerprints, raisins, and microlenses.

As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses.

STANFORD-DESIGNED HAPKIT BRINGS PHYSICAL TOUCH TO THE VIRTUAL CLASSROOM.

National Science Foundation grant allows Stanford Engineering team to experiment with a way to combine online learning with hands-on experience.

Stanford educators have designed a do-it-yourself kit that gives online learners hands-on experience by bringing haptics into virtual classrooms.
Haptics refers to the sense of touch. The hands-on teaching tool is called Hapkit. Hapkit has a sensor, motor and controller board that can be programmed using a personal computer. Learners can program Hapkit to produce specific sensations. For instance a user should be able to touch the device and feel what it's like to run his or her hand against a wall or click a ballpoint pen.

STANFORD ENGINEERS DEVELOP A DEVICE FOR MEASURING HOW BIRDS TAKE FLIGHT.

A new device invented by Assistant Professor David Lentink will answer long-held questions about the forces birds generate while flying and could lead to the development of innovative, efficient unmanned aerial vehicles.

It's easy to look at a bird and deduce that it flies by flapping its wings, but understanding exactly how a bird generates lift has long eluded scientists. Now engineers at Stanford have developed a device that precisely and humanely measures the forces generated by a bird's wings while in flight. The work, published in the Royal Society journal Interface, promises to answer many mysteries of bird flight, providing aid in the design of innovative and efficient unmanned aerial vehicles, known as UAVs or, more recently, drones. Measuring the lift forces of a bird in free flight has been a holy grail for biomechanical engineers, said David Lentink, an assistant professor of mechanical engineering at Stanford and lead author on the new paper. But every technique developed so far has provided uncertain results.

Vision system for household robots.

New algorithm could enable household robots to better identify objects in cluttered environments.

For household robots ever to be practical, they'll need to be able to recognize the objects they're supposed to manipulate. But while object recognition is one of the most widely studied topics in artificial intelligence, even the best object detectors still fail much of the time.
Researchers at MIT's Computer Science and Artificial Intelligence Laboratory believe that household robots should take advantage of their mobility and their relatively static environments to make object recognition easier, by imaging objects from multiple perspectives before making judgments about their identity. Matching up the objects depicted in the different images, however, poses its own computational challenges.

STANFORD TEAM COMBINES LOGIC, MEMORY TO BUILD A 'HIGH-RISE' CHIP.

Stanford researchers are building layers of logic and memory into skyscraper chips that are smaller, faster, cheaper – and taller.

For decades, the mantra of electronics has been smaller, faster, cheaper.

Today, Stanford engineers add a fourth word – taller.

At a conference in San Francisco, a Stanford team will reveal how to build high-rise chips that could leapfrog the performance of the single-story logic and memory chips on today's circuit cards.

Those circuit cards are like busy cities in which logic chips compute and memory chips store data. But when the computer gets busy, the wires connecting logic and memory can get jammed.

The Stanford approach would end these jams by building layers of logic atop layers of memory to create a tightly interconnected high-rise chip. Many thousands of nanoscale electronic "elevators" would move data between the layers much faster, using less electricity, than the bottleneck-prone wires connecting single-story logic and memory chips today.

The work is led by Subhasish Mitra, a Stanford associate professor of electrical engineering and of computer science, and H.-S. Philip Wong, the Williard R. and Inez Kerr Bell Professor in Stanford's School of Engineering and a professor of electrical engineering. They describe their new high-rise chip architecture in a paper being presented at the IEEE International Electron Devices Meeting (IEDM) on Dec. 15-17.

New findings could point the way to "valleytronics".

Researchers clear hurdles toward a new kind of 2-D microchip using different electron properties.

New findings from a team at MIT and other institutions could provide a pathway toward a kind of two-dimensional microchip that would make use of a characteristic of electrons other than their electrical charge, as in conventional electronics. The new approach is dubbed “valleytronics,” because it makes use of properties of an electron that can be depicted as a pair of deep valleys on a graph of their traits.

The findings are described in a paper appearing in the journal Nature Materials, co-authored by MIT graduate student Edbert Jarvis Sie, MIT associate professor Nuh Gedik, and five others.

The material the team studied is called tungsten disulfide (WS2), which belongs to a class of 2-D crystals known as transition metal dichalcogenides (TMDs). Like the single-layer carbon material called graphene, TMDs form thin films with a hexagonal, chicken-wire-like structure just a few atoms in thickness. (In the case of graphene, it is just a single atomic layer, while the TMDs are three atoms thick.)

Controlling a material with voltage.

Technique could let a small electrical signal change materials’ electrical, thermal, and optical characteristics.

A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a new family of materials with a variety of switchable properties, the researchers say.

The technique could ultimately be used to control properties other than magnetism, including reflectivity or thermal conductivity, they say. The first application of the new finding is likely to be a new kind of memory chip that requires no power to maintain data once it’s written, drastically lowering its overall power needs. This could be especially useful for mobile devices, where battery life is often a major limitation.

Stanford scientists create a 'smart' lithium-ion battery that warns of potential fire hazards.

Stanford's Yi Cui and colleagues have created a lithium-ion battery that alerts users to potential overheating and fire.
Stanford University scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes. "Our goal is to create an early-warning system that saves lives and property," said Yi Cui, an associate professor of materials science and engineering. "The system can detect problems that occur during the normal operation of a battery, but it does not apply to batteries damaged in a collision or other accident."
