Spray On Solar Cells

An inch-long array of some of the tiniest solar cells ever built has been successfully tested as a power source for microscopic machines, a new study reports. Instead of using silicon, Xiaomei Jiang and her colleagues from the University of South Florida turned to a polymer (a long organic molecule made of repeating structural units). The polymer they selected has the same electrical properties as silicon wafers, but can be dissolved and printed onto flexible material. Jiang and her colleagues made 20 tiny cells - each the size of a lower case "o" in standard 12-point print - and joined them together in an array to power a microscopic chemical detector.

Flex-Core - Flexible Split-Core Current Transformer

The FCL model split-core current transformers have multiple benefits, including a flexible twisting motion for ease of application. Installing a split-core CT means there is no need to disconnect your primary conductor(s) which reduces downtime. Many customizations are available including extended secondary lead wire lengths, various outputs including 5A, 1A, 1VAC, and 0.333VAC, and custom rubber inserts to help center the CT and maintain accuracy. The FCL models can be used in applications up to 720VAC and have an operating frequency from 50Hz to 400Hz.
