3D Printing Progress

3D printing helps develop world-first hearing aid

A world-first self-fitting hearing aid with a rechargeable battery and the ability to be set via a smartphone has been developed with the help of Swinburne's ARC Training Centre in Biodevices.
The new age hearing aid will allow users to optimise their listening preference of the device via their smartphone, tablet or home computer.
The hearing aid, called "Facett", consists of two components - the `core' contains the user's settings and the `module' contains a rechargeable battery that activates the hearing aid.
Users can connect or disconnect the module with a simple click of the device.
Reducing audiologist visits
Swinburne's Adjunct Professor Elaine Saunders co-developed the hearing aid and says it will eliminate the need for regular visits to the audiologist.
"This is a huge leap in progress for the four million Australians suffering hearing loss, many of whom aren't using hearing aids because of appearance, repeated and frustrating visits to suppliers for hearing aid tuning and the inconvenience and complexity of changing batteries," Adjunct Professor Saunders says.
Adjunct Professor Saunders says Facett is the culmination of decades of work together with rapid advances in hearing technology.
"Facett is a true collaboration between science and design," she says. "It's part of a digital health system that empowers people to self-manage their hearing experience."
A wireless control system
Swinburne PhD candidate Jonathon Miegel also played a crucial role in the development of the Facett.
As part of his PhD project, Jonathon helped develop a low-power, wireless control system that communicates between personal electronic devices such as smartphones and hearing aids.
He says his role was in the early stages.
"I provided multiple designs for the modular connections, each of which provided different features aimed at improving the strength of the connection between modules without making the hearing aid too difficult to manipulate," he says. "The design and prototyping process was carried out in rapid iterations using a combination of computer-aided design software and various types of 3D printing. The work I conducted on the modular connection is to be submitted a part of my PhD."
