    Basic Information

Technology developed: Self powered straight cochlea basilar membrane to bypass the function of the damaged ear (TP19763078189)
Category: Product (Hardware/Material/Software)
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. Aparna Zagabathuni, Dr. S. Kanagaraj Indian Institute of Technology Guwahati Mechanical Engineering Institute Post-Doctoral Fellow, Professor
Technical Application Area: Healthcare
If 'Other', please specify:
Please give more details of new technical application area:
Self-powered straight cochlea basilar membrane is expecterd to substitute the convebntioanl cochlear implnat composed of a microphone and a signal processor for detecting sound and frequency selectivity. It can assist the patients, who suffer from deafness by directly stimulating the auditory nerves bypassing the damaged portion of the inner ear and thus helps to provide or restore functional hearing without external power supply. being a self powered device, via piezoelectric unit is expected to work without any requirement of power supply.

Category of Technology developed: Immediate Deployment
Stage of Development: Lab-Scale
Please describe in detail including the TRL Level:
Self-powered straight cochlea basilar membrane (cantilever array beam) covering the human frequency range i.e., 20 Hz to 20 kHz without any external power supply has been designed and will be fabricated using micro electro mechanical system (MEMS) technology. The cantilever beam consists of AlN as a piezoelectric material, Mo as a bottom electrode, Au as a top electrode, and Al as a proof mask. Different ranges of frequency (13 Hz - 23 kHz) have been achieved by varying the length of the cantilever beam and by keeping width constant. The electric potential generated from the cantilever beam can directly stimulate the auditory nerves. Now the finbal prototype is under fabrtication phase and fabrication process will be carried out at IISC Banglore.


Applications: The high power consumption social stigma lifestyle of patients high cost etc preclude some severe to profound hearing loss patients from using or even considering the cochlear implant device Therefore a selfpowered straight cochlear basilar membrane has been designed to replace the function of the damaged inner ear without an external power supply
Advantages: The cochlear implant is being used to restore the hearing till date There are so many limitations with cochlear implants such as large power consumption frequent battery replacement mechanical malfunctioin by external impact high cost inconvenient in daily usage etc The present device selfpowered straight cochlear basilar membrane having a frequency range of 20 Hz to 20 kHz with the required electrical potential can directly stimulate the auditory nerves with out any external power supply Compared to the existing conventional cochlear implant the present device is least expensive Mass production is possible for this selfpowered straight cochlear basilar membrane by the micronanofabrication process which further reduces the cost of the device

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
