The new design is in response to a growing number of phones and media players that are shrinking in size but still need connection technology. It is expected to replace the current Mini-USB standard.
Handset giant Nokia welcomed the news. "Nokia always strives for great user experience," said Jouko Junkkari, a director within Nokia Technology Platforms.
"The new Micro-USB that is standardised, miniaturised, and optimised for mobile use helps us in that important task.
"The Micro-USB offers innovative design and a flexible platform that our technical teams can easily take on board while working with new product designs."
The new design also differs from standard USB in that the connector is much more robust. It will be made with a stainless steel shell designed to withstand more than 10,000 insertions.
"As phones, PDAs and cameras get smaller and more compact, manufacturers need a new USB connector specification to suit the design of these new products," said Jeff Ravencraft, chairman and president of the USB-IF.
Micro-USB will also support the USB On-The-Go standard, which allows devices to link via USB without involving a PC.
