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.

Wearable Nanowire Sensors Monitor Electrophysiological Signals
Posted in News, News, Electronic Components, Patient Monitoring, Sensors on Wednesday, 21 January 2015
Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used in hospitals, but can be used for long-term monitoring and when a patient is moving.
