Research Bits: Oct. 22


3D-printed active electronics Researchers from MIT demonstrated fully 3D-printed semiconductor-free resettable fuses. Produced using standard 3D printing hardware and an inexpensive, biodegradable polymer filament doped with copper nanoparticles, the device can perform the same switching functions as the semiconductor-based transistors used for processing operations in active electronics. A... » read more

3D-Printed Logic Gates and Resettable Fuses, Via Material Extrusion (MIT)


A new technical paper titled "Semiconductor-free, monolithically 3D-printed logic gates and resettable fuses" was published by researchers at MIT. "This work reports the first active electronics fully 3D-printed via material extrusion, i.e. one of the most accessible and versatile additive manufacturing processes. The technology is proof-of-concept demonstrated through the implementation of ... » read more

3D printing of specialized antennas, sensors Researchers from the National University of Singapore developed a 3D printing technique that can be used to create three dimensional, self-healing electronic circuits. Called tension-driven CHARM3D, the technique enables the 3D printing of free-standing metallic structures without requiring support materials and external pressure. It uses Field�... » read more

Micro Dispensing: From Semiconductors To Sushi


The phrase “micro fluid dispensing” is generally associated with applications like medical device assembly or battery manufacturing. It certainly doesn’t conjure up visions of sushi – at least not yet. If engineers at IHI Aerospace and Yamagata University have their way, though, 3D printed sushi will be served to space tourists as they circle in low Earth orbit. Yes, printed sush... » read more

Weaving A Digital Thread For Design And Manufacture Of Additive Electronics


Additive manufacturing has been around electronics since thick-film, screened hybrids came on the scene more than 30 years ago. And while those never quite went away, they never gained the prominence we all expected alongside the more traditional laminated, subtractive-etched PCBs. Today, emerging technologies are bringing a resurgence in additive manufacturing, also known as printed electro... » read more

Printing Grids In 3D


Those of you who attended the 2011 Pointwise User Group Meeting may remember that our company president, John Chawner, mentioned during his closing statements how nice it would be to have the ability to print your grids in 3D. That was more than just a dreamy, "what if" statement. It is a reality! Almost. A little history 3D-printed F-16 forward fuselage. I have always been fascinat... » read more

Micropatterning with sugar A scientist at the National Institute of Standards and Technology (NIST) discovered a transfer printing process that can deposit microcircuit patterns on curved and textured surfaces using sugar candy. Transfer printing methods, such as flexible tapes, are often used for surfaces that are difficult to directly print on. But they have difficulty with conforming to ... » read more

Unknowns And Challenges In Advanced Packaging


Dick Otte, CEO of Promex Industries, sat down with Semiconductor Engineering to talk about unknowns in material properties, the impact on bonding, and why environmental factors are so important in complex heterogeneous packages. What follows are excerpts of that conversation. SE: Companies have been designing heterogeneous chips to take advantage of specific applications or use cases, but th... » read more

Ionic circuit for neural nets Researchers at Harvard University and DNA Script developed an ionic circuit comprising hundreds of ionic transistors for neural net computing. While ions in water move slower than electrons in semiconductors, the team noted that the diversity of ionic species with different physical and chemical properties could be harnessed for more diverse information process... » read more
