Abstract: A microfluidic device which comprises a microelectronic chip that is remotely coupled to external power and data sources. The device includes a body structure, at least one microscale channel within the structure, a port for introducing fluid into the channel, a microelectronic chip internal to the structure, and a power source external to the structure coupled remotely to said structure by non-contact means. Various structures are described which embody the invention.

Abstract: A molded glove defines a hand and wrist portion, with the wrist portion defining, in as-molded configuration, longitudinal channels positioned about its circumference. In accordance with this invention, a plurality of circumferential channels are defined on the wrist portion at the end remote from the hand portion, the circumferential channels crossing the longitudinal channels. The thickness of the glove along the longitudinal and circumferential channels is increased over the thickness of the glove in areas adjacent to the channels. The glove exhibits improved resistance to rolling down of the cuff while being worn, when compared with conventional gloves having longitudinal flutes or channels, gloves having beaded cuffs, and the like.
