- *Abstract
-
As micro- and nano-scale electromechanical systems become commercially established, the widespread success of these products will be hindered unless testing methods and standards are developed to measure the properties of these products. Currently, the lack of testing methods and standards makes it difficult for customers to specify their requirements, and manufacturers to specify the properties of their products. Furthermore, testing standards for these micro- and nano- scale products are difficult to develop because they are prone to numerous uncertain properties due to their extreme sensitivity to process variations in how they are both fabricated and tested. While a few testing standards exist, their relatively high costs, long duration and uncertain accuracy make them nonideal for facilitating the growth of these emerging products.
To address these issues, researchers at UC Berkeley have designed an electromechanical device and developed associated analysis techniques that make the measuring of micro- and nano- scale systems commercially viable. This compact device can fit inside a 1 mm by 1 mm square or smaller. It can accurately measure in-plane over- or under- cut, effective Young's Modulus, and the comb-drive force for the material and process in which it was made.
In contrast to other similar techniques, this device and the methods used to measure properties are more accurate and economical.
