Biodegradable computer chips made almost entirely from wood

By - May 28, 2015 1 Picture

As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem. That's why scientists from the University of Wisconsin-Madison have started producing "wooden" semiconductor chips that could almost entirely biodegrade once left in a landfill. As an added bonus, the chips are also flexible, making them prime candidates for use in flexible electronics.

Safe, wirelessly charged implants could replace drugs

By - May 20, 2014 5 Pictures
Researchers at Stanford University have developed a new way to safely transfer energy to tiny medical devices implanted deep inside the human body. The advance could lead to the development of tiny "electroceutical" devices that can be implanted near nerve bundles, heart or brain tissue and stimulate them directly when needed, treating diseases using electronics rather than drugs.

Chips with collaborating CPU and GPU lead to faster processors

By - February 7, 2012 1 Picture
Want to get your computer to run faster? Well, consider its graphics processing unit (GPU) and central processing unit (CPU). The two work away at their own tasks, each one rarely helping the other shoulder its workload. Researchers from North Carolina State University, however, are in the process of changing that. They have already developed a technique that allows GPUs and CPUs located on a single chip to collaborate on tasks, and it has resulted in a processing speed increase of over 20 percent. Read More

IBM experimental chips emulate the human brain

By - August 18, 2011 1 Picture
In April, the University of Southern California made the headlines when it announced that researchers there had created a functioning synthetic synapse circuit using carbon nanotubes. Well, today IBM unveiled a new class of experimental computer chips that are designed to emulate the human brain’s abilities for perception, action and cognition. According to the company, “The technology could yield many orders of magnitude less power consumption and space than used in today’s computers.” Read More

IBM demonstrates multi-bit phase-change memory chip

By - June 30, 2011 1 Picture
Scientists from IBM Research – Zurich are claiming a world-first, for their recent demonstration of “reliable multi-bit phase-change memory [PCM] technology.” PCM involves the use of materials that change between crystalline and amorphous states, the two states having different levels of electrical resistance – data is stored in a binary fashion, using one level to represent a 0, and the other to represent a 1. By applying new techniques to existing PCM technology, the researchers were reportedly able to write and retrieve data 100 times faster than is possible with Flash. Read More

Researchers demonstrate self-repairing chip

By - March 16, 2011 2 Pictures
As chips continue to get smaller, the technological possibilities just get larger. One of the trade-offs of miniaturization, however, is that smaller things are also often more fragile and less dependable. Anticipating a point at which chips will become too tiny to maintain their current level of resilience, a team of four companies and two universities in The Netherlands, Germany, and Finland have created what they say could be the solution – a chip that monitors its own performance, and redirects tasks as needed.

Shrinking integrated circuits a big deal for microelectronics

By - July 16, 2010 2 Pictures
The miniaturization of electronics has seen the wiring of connections between chips and circuit boards become a substantial obstacle. Such connections are traditionally made from pre-fabricated metal wires that connect to a designated bonding pad on a chip. However, many microelectronic devices are much smaller than the required 50-by-50 micron square bonding site, prohibiting integrated functions on a very small scale. Engineers at the University of Illinois have now developed a novel direct-writing method for manufacturing metal interconnects that could enable the further shrinking of integrated circuits and expand microelectronics.
