Seamless Integrated Circuits Etched on Graphene

Researchers at UC Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-dimensional plane of carbon atoms. The demonstration offers possibilities for ultra energy-efficient, flexible, and transparent electronics.

Transient Electronics Dissolve When Triggered

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.To demonstrate that potential, Montazami played a video showing a blue light-emitting diode mounted on a clear polymer composite base with the electrical leads embedded inside. After a drop of water, the base and wiring began to melt away. As the technology develops, Montazami sees more and more potential for the commercial application of transient materials. A medical device, once its job is done, could harmlessly melt away inside a person’s body. A military device could collect and send its data and then disappear, leaving no trace of an intelligence mission. An environmental sensor could collect climate information, then wash away in the rain. SourceAlso: Read other Electronics & Computers tech briefs.

Wireless Device Senses Chemical Vapors

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad applications in military, commercial, environmental, and healthcare areas.The current design integrates nanotechnology and radio-frequency identification (RFID) capabilities into a small working prototype. An array of sensors uses carbon nanotubes and other nanomaterials to detect specific chemicals, while an RFID integrated circuit informs users about the presence and concentrations of those vapors at a safe distance wirelessly.Because it is based on programmable digital technology, the RFID component can provide greater security, reliability and range – and much smaller size – than earlier sensor designs based on non-programmable analog technology. The present GTRI prototype is 10 centimeters square, but further designs are expected to squeeze a multiple-sensor array and an RFID chip into a one-millimeter-square device printable on paper or on flexible, durable substrates such as liquid crystal polymer.SourceAlso: Learn about Extended-Range Passive RFID and Sensor Tags.

2013 Create the Future Design: Electronics Category Winner

iPecs Pro Clinical Prosthetic Alignment and Assessment Tool Michael Leydet, Richard Harrington, Alan Hutchenreuther, Vinay Bharadwaj, Chuck Krapf, Michael Link, Megan Toscas, Steven Hoover, Chris Nowak, Aaron Taszreak, Douglas Briggs, and Frank Fedel College Park Industries Inc., Warren, MI iPecs Pro Historically, the fitting, adjustment, and alignment of prosthetic devices has been a highly skilled art relying on the training and experience of the prosthetist with input from the patient, but with limited access to objective quantifiable measures. The iPecs Pro software will have clinical real-time functional assessment features. This will guide the user through a series of subjective and objective questions and physical tests to determine the functional level of the patient. A report using the scale of the questions and the measured results from the physical tests will be produced for summation to the payer as support of the prostheses selection and prescription. After the sensor is used on each patient, the iPecs Pro will be removed and iPyramid (dummy unit or replacement adaptor) is placed into the prosthetic build as a placekeeper for future visits.

Electron Beam Writer Enables Microfabrication

Integrated electronics could activate prosthetics. The new electron beam writer housed in the cleanroom facility at the Qualcomm Institute, previously the UCSD division of the California Institute of Telecommunications and Information Technology, is important for two major areas of research by Shadi Dayeh, PhD, an electrical and computer engineering professor. He is developing next-generation, nanoscale transistors for integrated electronics. At the same time, he is working to develop neural probes that can extract electrical signals from brain cells and transmit the information to a prosthetic device or computer. To achieve this level of signal extraction or manipulation requires tiny sensors spaced very closely together for the highest resolution and signal acquisition. Enter the new electron beam writer. (See Figure 1)
