Self-Powered Intelligent Keyboard Could Provide Additional Security
Posted in News, Board-Level Electronics, Computers, Electronic Components, Electronics, Power Management, Energy Harvesting on Wednesday, 18 February 2015
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

Zinc Oxide Materials Power Tiny Energy Harvesting Devices
Posted in News, Electronic Components, Energy Harvesting, Renewable Energy, Metals on Wednesday, 11 February 2015
Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable, and powered by ambient renewable energy. This last goal inspired researchers to explore how the attractive physical features of zinc oxide (ZnO) materials could be used to tap into abundant mechanical energy sources to power micro devices. They discovered that inserting aluminum nitride insulating layers into ZnO-based energy harvesting devices led to a significant improvement of the devices’ performance. The group’s findings are expected to provide an effective approach for realizing “nanogenerators” for self-powered electronic systems such as portable communication devices, healthcare monitoring devices, environmental monitoring devices, and implantable medical devices.

Glass as Electrode Makes Batteries More Efficient
Posted in News, Batteries, Electronic Components, Energy Efficiency on Wednesday, 11 February 2015
Today’s batteries provide a reliable power supply for our smartphones, electric cars and laptops, but are unable to keep up with the growing demands placed on them. Researchers have discovered a material that may have the potential to double battery capacity: vanadate-borate glass. The glass is being used as a cathode material, which is made of vanadium oxide (V2O5) and lithium-borate (LiBO2) precursors, and was coated with reduced graphite oxide (RGO) to enhance the electrode properties of the material. The vanadate-borate glass powder was used for battery cathodes, which were placed in prototypes for coin cell batteries to undergo numerous charge/discharge cycles. In tests, the glass electrodes demonstrated a vast improvement in these batteries’ capacity and energy density. Source:

Serial Communication Cards
Posted in Products, Electronic Components on Sunday, 01 February 2015
ACCES I/O Products, San Diego, CA, announced mPCIe-ICM Series PCI Express Mini Card isolated serial communication cards that measure 30 × 51 mm and feature a selection of four or two ports of isolated RS-232 serial communications. Features include 1.5kV isolation provided port-to-computer and 500V isolation port-to-port on all signals at the I/O connectors. The cards provide ±15kV ESD protection on all signal pins, and use 128-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multitasking systems.
