Xerox Corp. (http://rbi.ims.ca/3849-537) has developed a new semiconductive ink and other new materials that may make printing complete plastic transistor circuits possible. Xerox says the new ink can be used to print the semiconductor channels of transistors at low temperature and in open air—a feature that's critical for low-cost manufacturing, as the electrical properties of most liquid-processable organic semiconductors degrade when exposed to atmospheric oxygen, making it difficult to build functional transistors.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
