This applications note discusses a low-cost circuit for I2C level translation. This circuit was developed for the Si701x, Si702x, and Si703x humidity sensors but will work in many applications. This circuit provides I2C level translation from a higher voltage supply, such as 5 V, to a lower voltage, supply such as 1.8 or 3.3 V. […]

U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a way to assemble transistors based on the 2D materials graphene and molybdenum disulfide. The method etches narrow channels in conducting graphene laid down on a silicon-dioxide substrate. These channels are then filled with a transition-metal dichalcogenide, or TMDC, or more specifically MoS2.

Description TritiLEDs are always-on battery powered LED glow lights for general night-time marking use. Radioactive gaseous tritium light sources (GTLSs) are allowed in the United States in several consumer product categories, including watches, compasses, and gun sights, but general-purpose markers are considered “frivolous” and are prohibited. Levaraging advances in LED efficiency, battery capacity, and microcontroller
Infineon will have engineering samples of a 3D magnetic sensor in July. Called TLV493D-A1B6 performs magnetic field detection in x, y, and z direction allowing the sensor to measure 3D linear and rotation movements. The digital I²C interface enables bidirectional communication between sensor and microcontroller.The sensor is for consumer and industrial applications that require 3D
