Using ultrasound to deliver power wirelessly, Stanford researchers are working on a new generation of medical devices that would be planted deep inside the body to monitor illness, deliver therapies and relieve pain.
Medical researchers would like to plant tiny electronic devices deep inside our bodies to monitor biological processes and deliver pinpoint therapies to treat illness or relieve pain.
But so far engineers have been unable to make such devices small and useful enough. Providing electric power to medical implants has been one stumbling block. Using wires or batteries to deliver power tends to make implants too big, too clumsy – or both.

Stanford engineers developing miniature wireless device to create better way of studying chronic pain
A team of Stanford engineers is creating a small wireless device that will improve studies of chronic pain. The engineers hope to use what they learn to develop better therapies for the condition, which costs the economy $600 billion a year.
Ada Poon, a Stanford assistant professor of electrical engineering, is a master at building minuscule wireless devices that function in the body and can be powered remotely. Now, she and collaborators in bioengineering and anesthesia want to leverage this technology to develop a way of studying – and eventually developing treatments for – pain.

New classes allow undergraduates to use EE tools and techniques to make gizmos and systems from day one.
Undergraduate Diniana Piekutowski, EE '16, came to Stanford with an interest in sustainability that she could have pursued through several different majors.
“I eventually decided on Electrical Engineering because I wanted to learn the essence of energy and electronics,” Piekutowski said. “To me, EE is a harmonic balance of theory and application.”

Costing just pennies to make, tiny radios on a chip are designed to serve as controllers or sensors for the 'Internet of Things.'
A Stanford engineering team, in collaboration with researchers from UC Berkeley, has built a radio the size of an ant, a device so energy efficient that it gathers all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna – no batteries required.
Designed to compute, execute and relay commands, this tiny wireless chip costs pennies to fabricate – making it cheap enough to become the missing link between the Internet as we know it and the linked-together smart gadgets envisioned in the "Internet of Things."

A wireless system developed by Assistant Professor Ada Poon uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.

Research revealing the neural basis for why learning new tasks can be difficult could lead to improved therapies for stroke and other brain injuries.
Scientists from Carnegie Mellon University, the University of Pittsburgh and Stanford have discovered a fundamental constraint in the brain that may explain why people have a relatively easier time learning new skills if they are related to abilities they have already mastered.

Siegman International School on Lasers, named in honor of a deceased Stanford engineer who was a colossus in this important field, completes its inaugural session.
The new Siegman International School on Lasers at Stanford functions as a tacit acknowledgement of the ubiquity and importance of laser technology. Fifty years ago, lasers were a curiosity. Today, they are deeply embedded in virtually every technological sector: medicine, aviation, communications, energy production, automobiles and agriculture.

Stanford Engineering student wins international competition for efforts to miniaturize ultrasound device
PhD candidate in electrical engineering says encouragement from his advisor helped propel him toward $10,000 cash prize.
A Stanford Engineering student won the $10,000 first place prize at the third annual Broadcom Foundation University Research Competition.
Jonathon Spaulding, a Stanford PhD student in electrical engineering, hopes to build smaller, cheaper, and more efficient handheld ultrasound systems.
“Imagine having these devices in every doctor’s office, or taking ultrasound scanners into the field where imaging technology is limited,” Spaulding said, adding that he is continuing work in the hope of developing a hardware prototype the size of a common flash drive.

By adding a specially patterned layer of silica glass to the surface of ordinary solar cells, a team of researchers led by Professor Shanhui Fan has found a way for the cells to shed unwanted thermal radiation.
Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells – keeping them cool, even in the blistering heat of the noonday Sun.
