As you all surely know, there are no such things as sounds out there, there are only pressure waves generated by the interactions between objects and that travel through the air, eventually these pressure waves reach a membrane called the eardrum located in our middle ear making the membrane vibrates.

Como seguramente todos sabéis, allá afuera no existen eso que llamamos sonidos, tan solo existen ondas de presión generadas por las interacciones entre objetos y que viajan a través del aire, eventualmente estas ondas de presión alcanzan una membrana llamada tímpano situada en nuestro oido medio haciendo que la membrana vibre.

These vibrations of the membrane run through a chain of ossicles that finally convert these vibrations into electrical stimuli that are sent through the optic nerve to our brain, once there the brain analyzes these electrical impulses and identifies them as a scream, a fart or the Beethoven's 5th Symphony.

Estas vibraciones de la membrana recorren una cadena de huesecillos que finalmente convierten esas vibraciones en estímulos eléctricos que son enviados a través del nervio óptico hasta nuestro cerebro, una vez allí el cerebro analiza estos impulsos eléctricos y los identifica como un grito, un pedo o la 5º sinfonía de Beethoven.

Of all these elements, the most complex is the cochlea, a structure in the form of a tube wound in a spiral where specialized cells convert external vibrations into electrical impulses, when it stops working we lose our hearing and that is when the experts install a cochlear implant, which is a device that performs the functions of that spiral tube.

De todos estos elementos el más complejo es la cóclea, una estructura en forma de tubo enrollada en espiral donde unas células especializadas convierten las vibraciones externas en impulsos eléctricos, cuando ésta deja de funcionar perdemos el oído y es cuando los expertos nos instalan un implante coclear que es un dispositivo que haces las funciones de ese tubo en espiral.

The effectiveness of these implants depends on the way the current propagates and this is affected by the high conductivity of the fluids found in the inner ear that add a lot of noise to the hearing, given the lack of accessibility to the organ and Taking into account that each cochlea has a unique design for each individual, it is very difficult to collect data that allows us to understand how the current propagates.

La eficacia de estos implantes depende de la forma en que se propaga la corriente y esta se ve afectada por la alta conductividad de los fluidos que se encuentran en el oido interno que añaden mucho ruido a la audición, dada la falta de accesibilidad al órgano y teniendo en cuenta que cada cóclea tiene un diseño único para cada individuo resulta muy difícil recopilar datos que permitan entender como se propaga la corriente.

A multidisciplinary team of engineers and doctors used 3D printing to create intricate models of human cochlea and applied machine learning to them to be able to predict current flows in each design and improve hearing conditions in patients using cochlear implants.

Un equipo multidisciplinar de ingenieros y médicos utilizaron la impresión 3D para crear intrincados modelos de cócleas humanas y sobre ellas aplicaron aprendizaje automático para poder predecir los flujos de la corriente en cada diseño y mejorar las condiciones de la audición en los pacientes que utilizan implantes cocleares.

According to its creators, the next step would be to apply these technologies and knowledge to model other parts of the auditory process and to better understand how these nervous stimuli spread throughout the middle and inner ear.
With all this, increasingly effective implants can be developed that restore patients to their natural hearing ability.

Según sus creadores el próximo paso sería aplicar estas tecnologías y conocimientos para modelar otras partes del proceso auditivo y poder entender mejor como se propagan estos estímulos nerviosos por todo el oído medio e interno.
Con todo esto se podrán desarrollar implantes cada vez más eficaces que devuelvan a los pacientes su facultad auditiva natural.

Hello @mauromar, What a great north, this is one of the best utilities of 3D impressions that I have read recently, I think that prosthesis solutions will get the best advantages with 3D printing, because it will not only be the cochlear implant, surely many other parts of the body human beings can be solved in this way.

I hope ;-D

Congratulations for such an interesting contribution, AI plus Biotechnology leads us to a better quality of life to those who require it and reading these advances is satisfying, thank you for the contribution,

Hola @mauromar, nuestro cuerpo sí que es complejo y avanzado.

As always, interesting topic. Welcome to advances in science. Blessings.

And the best of all is that people with these implants can live a life with only some restrictions such as avoiding contact sports to avoid damage to the device and another point is that people with these implants cannot have MRIs. since the implant has metal parts. Thanks for sharing, very good topic.

Thank you very much for sharing this information mate.

Learn some new from your post. Love to read it.
