The world's smallest hearing aid named Nanoplug was developed by an international team of researchers. The development of Nanoplug was revealed in the fourth week of December 2014 in The Times of India.
The concept of Nanoplug was first conceived by Nevena Zivic and then brought to execution by industrial designer, Jongha Lee, audio engineer Mladen Stavri and electromechanical engineer Zoran Marinovi.
The Nanoplug is so tiny that it is almost undetectable. The designing of this hearing aid was funded through Indiegogo, a crowdfunding platform.
The development of device was made possible by advances in Nanotechnology, most notably by the US Photonics Endure nanobattery that is as about the size of a grain of sand and is able to work six days without recharge.
Highlights of the Nanoplug
• Nanoplug is comprised of micro-components and a nano-battery.
• The hearing aid is meant to be less intrusive, less noticeable and less expensive.
• The device is just 7.1mm x 5.7mm x 4.17mm, which is half the size of any other hearing aid.
• As claimed by the researchers, hearing aid battery has no toxic chemicals inside, nor heavy metals.
• Nanoplug can be programmed using software running on a computer, the results of which can be downloaded directly to the device via a cable.
• The Nanoplug is shaped roughly rectangular, it is placed inside a mushroom shaped sleeve which allows for comfort in keeping the hearing device securely in place.
• A tool is also provided for removal of the hearing aid.
• The Nanoplug does not entirely fill the ear canal which means it allows sound to be localized.
