The size of wireless electronic goods such as mobile phones and headphones is about to get a whole lot smaller with the Chinese University's invention of the world's tiniest Bluetooth communication module.

Professor Wu Keli, of the university's electronic engineering department, said the new module is as small as a mobile phone SIM card - half the size of units now in use - and could be applied to electronic products including laptops, MP3 players and digital cameras.

Until now, antennas have been too large to be incorporated with other components into Bluetooth headsets, but Professor Wu said: 'Our compact antenna is much smaller and can be mounted on the module. The size is thus minimised.'

The university has already filed a patent application.

Professor Wu said the device could also improve the efficiency of communication equipment and lower production costs.

'The working distance of such technology is more than 17 metres, while the present ones can only be supported over 10 metres,' he said.

'The cost of electronic products installed with our device will also be lowered as the whole size of the product is smaller, and materials used are naturally fewer.'

The communication module, which took 18 months to develop, was sponsored by the government's Innovation and Technology Commission, which contributed more than $3 million.

About six Hong Kong and mainland companies have already expressed interest in incorporating the device into their products.

'A local headset producer is planning to produce a super-mini headset with this technology,' Professor Wu said.
