Power/Performance Bits: April 13


Speedy data transfer Researchers from MIT, Intel, and Raytheon developed a new data transfer system that both boosts speeds and reduces energy use by taking elements from both traditional copper cables and fiber optics. "There's an explosion in the amount of information being shared between computer chips -- cloud computing, the internet, big data. And a lot of this happens over conventiona... » read more

Power/Performance Bits: March 8


Non-toxic, printable piezoelectric Researchers at RMIT University and University of New South Wales developed a flexible and printable piezoelectric material that could be used in self-powered electronics including wearables and implantables. "Until now, the best performing nano-thin piezoelectrics have been based on lead, a toxic material that is not suitable for biomedical use," said Dr N... » read more

Thinner, flexible touchscreens Researchers from RMIT University, University of New South Wales, and Monash University developed a thin, flexible electronic material for touchscreens. The material is 100 times thinner than current touchscreen materials. The new screens are still based on indium-tin oxide (ITO), a common touchscreen material. However, a liquid metal printing approach was used... » read more

Textiles for energy storage Scientists at RMIT University developed a way to laser print waterproof textiles with graphene supercapacitors for embedded energy storage. The process takes three minutes to create a 10x10cm patch. The electronic textile is based on nylon coated with PDMS on one side for waterproofing. The other side was paint coated with graphene oxide and a binder to form thin... » read more

Wearable heart monitoring Researchers at the University of Texas at Austin developed a lightweight, stretchy heart monitoring patch that can be worn externally. Along with being easy to wear, the graphene-based 'e-tattoo' is more accurate than existing electrocardiograph machines, according to the team. The e-tattoo measures cardiac health using both electrocardiograph and seismocardiograph... » read more

Reading qubits faster Researchers at Aalto University and VTT Technical Research Centre of Finland propose a faster way to read information from qubits, the building blocks of quantum computers. Currently, they are extremely sensitive to disruption even in cryogenic environments, holding quantum information for less than a millisecond. In the method now used to read information from a qubit... » read more
