Research Bits: Jan. 3


Printing electronics on curved surfaces Researchers from North Carolina State University have demonstrated a new technique for directly printing electronic circuits onto curved and corrugated surfaces. They have used the technique to create prototype “smart” contact lenses, pressure-sensitive latex gloves, and transparent electrodes. “There are many existing techniques for creating pr... » read more

Research Bits: May 24


Printed flexible OLED display Researchers from the University of Minnesota Twin Cities and Korea Institute of Industrial Technology used a customized 3D printer to print a flexible OLED display. “OLED displays are usually produced in big, expensive, ultra-clean fabrication facilities,” said Michael McAlpine, a professor in the Department of Mechanical Engineering at University of Minnes... » read more

Screen Printed Chipless RFID Tags on Packaging Substrates


Abstract: "A chipless radio frequency identification (RFID) tag is a suitable low-cost alternative to any chip-based RFID one. The flexibility to use low-cost printing techniques makes chipless RFID a competitive technology. In this paper, we report an evaluation of the microwave performance of two different screen-printed chipless tags in the 3–6 GHz range. The tags were designed and scre... » read more

Dual Surface Architectonics for Directed Self‐Assembly of Ultrahigh‐Resolution Electronics


Abstract: "The directed self‐assembly of electronic circuits using functional metallic inks has attracted intensive attention because of its high compatibility with extensive applications ranging from soft printed circuits to wearable devices. However, the typical resolution of conventional self‐assembly technologies is not sufficient for practical applications in the rapidly evolving addi... » read more

Power/Performance Bits: Oct. 11


Finer printed circuits Researchers from the National Institute for Materials Science in Japan, Jiangnan University, Zhengzhou University, Senju Metal Industry Co., and C-INK Co. developed a way to print smaller features for printed electronics. The directed self-assembly method increases the chemical polarity of predetermined areas on a surface, which promoted selective adhesion of metallic na... » read more

Power/Performance Bits: March 30


Harvesting body heat Researchers at University of Colorado Boulder, Harbin Institute of Technology, Southeast University, and Huazhong University of Science and Technology designed a stretchy thermoelectric generator that can be worn against the skin to power small wearable electronics using body heat. The stretchy material polyimine is used as the base of the device. A series of thin therm... » read more

Quiet qubits Researchers at the University of New South Wales Sydney recorded the lowest noise levels yet for a semiconductor qubit. Charge noise caused by material imperfections interferes with the information encoded on qubits, reducing accuracy. "The level of charge noise in semiconductor qubits has been a critical obstacle to achieving the accuracy levels we need for large-scale error-c... » read more

More stable quantum states Researchers at the University of Chicago found a way to make quantum systems retain coherency 10,000 times longer. The fragile nature of quantum states remains a challenge for developing practical applications of quantum computing, as they can be easily disrupted by background noise coming from vibrations, temperature changes or stray electromagnetic fields. Ap... » read more

Make Way For Flexible ICs


The push to develop intelligent sensors everywhere does not require everything to be on a silicon substrate. In fact, a growing part of the market increasingly is focused on flexible substrates. The market for printed sensors is roughly $3.6 billion today, according to a new report by IDTechEx. In a decade, that number is expected to grow to $4.5 billion, according to the firm, with growth i... » read more

Power/Performance Bits: April 14


Undoped polymer ink Researchers at Linköping University, Chalmers University of Technology, University of Washington, University of Cologne, Chiba University, and Yunnan University developed an organic ink for printable electronics that doesn't need to be doped for good conductivity. "We normally dope our organic polymers to improve their conductivity and the device performance. The proces... » read more
