Heated lattice tungsten filaments can emit more energy than solid tungsten filaments—a discovery that could meet the increasing power demand in advanced electrical applications such as hybrid electric cars—says an analysis by Technical Insights (www.technical-insights.frost.com). With crystalline regularity, tungsten lattices are capable of bending light without losing any energy, exhibiting a conversion efficiency of 34% and electrical power density of about 14 W/cm2 when heated to 1,250 centigrade. Thanks to computer chip production technology, they can now be mass-fabricated.
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.”
