Biomimetics is the learning of the structure and function of biological systems as models forthe design and engineering of material and machines . In other words , we cansay that it is recollection of nature, models, systems, processes and elementsto take inspiration from it in order tosolve problem faced by human. Biomimetics is the process of incorporatingprinciple that would that would promote sustainability in the same way thenature does from cradle to grave, from raw material to recycling it , in theworld especially in the physical world. The word biomimetics is derived from “bios” means life and mimesis means to imitate whichis introduced by Schmitt. It is the scientific method of learning newprinciples and processes based on systemic study and observations with liveanimals and organisms for practical solutions to future technology.Biomimetics is principle be appliedin many fields. Because of the complexity of biological systems, the number offeatures that might be imitated is large.
Biomimetic applications are atvarious stages of development from technologies that might become commerciallyusable to prototypes. And i have learned a lotin this course that how a technology id developed by observing the nature andit was proved as really good and new experience for me to learn aboutbiomemtics science. KEY LEARNINGS AND EXPERIENCE:As this subject is new to me , Igain much more knowledge on various aspects of nature and the lecture delievedby sir was very impressive and attractive. I able to understand each and everything very clearly and effectively.
It is really nice to haveProf. George john having a session on biomemtics. It is good experience ofhaving such session in which I had gain knowledge about a subject which was notthere in my course (b.sc). There are various kinds of examples related to lotusleaf, fibre food material, whale wind turbines, king fisher and the Shinkansenetc. Lots of learning are there in this session and which will help me intaking various decisions related to technology in future.and following are my key learnings:Ø It helps us to analyse natural mechanisms and thus make ourlives easy and smooth.
Ø Biomimetics is a platform where one can discover new deviceswith inspiration from nature.Ø Many researchers came up with ideas ,device and views likeinspiration from birds for flightsstability etc. In the class we came to know about technologiesand thinking involved behind the things that we are using in our daily life. Thesetechnologies were invented from the phenomena occuring from the nature.· This course hasfamiliarized us with some of the process and method ofestablishing principals throughobservation, experimentation and construction model of living organism.biomemetic product aresuccessful in market. They are very resource efficient and have a very highdegree added value . hence the future development of these products will helpsus a lot.
A MOSQUITOS INSPIRED STRATEGY TO IMPLANTMICROPROBES INTO THE BRAIN : Mosquitos are the lifethreatening insects on the planet due to their ability to transmitdiseases like malaria through their bite. In order to bite, a mosquito mustinsert a set of micro-sized needles through the skin to reach vascularstructures. The mosquito uses a combination of mechanisms including aninsertion guide to enable it to bite and feed off of larger animals. Here, wereport on a biomimetic strategy inspired by the mosquito insertion guide toenable the implantation of intracortical microelectrodes into the brain. Nextgeneration microelectrode designs leveraging ultra-small dimensions and/orflexible materials offer the promise of increased performance, but presentdifficulties in reliable implantation.
With the biomimetic guide in place, therate of successful microprobe insertion increased from 37.5% to 100% due to therise in the critical buckling force of the microprobes by 3.8-fold.
Theprototype guides presented here provide a reproducible method to augment theinsertion of small, flexible devices into the brain. In the future, similarapproaches may be considered and applied to the insertion of other difficult toimplant medical devices.The parasitic bite of a female mosquito allows it to bothinject an anticoagulant to thin the host’s blood, and then, like a miniaturehypodermic needle, suck out blood to aid in egg productionTo enable themosquito to penetrate the host’s skin with a set of blood-sucking needles,multiple mechanisms are employed. Specifically, the mosquito must increase the criticalbuckling force of each fascicle, while also reducing the force required topenetrate the skin.
A series of recent studies have discussed strategies takenby nature to prevent buckling .Categorized strategies to either increase thecritical buckling load, or conversely decrease the required penetration load.Interestingly, the mosquito does both, inspiring the design of “painless”microneedles.
We are particularly intrigued by the mosquito’s ability toincrease the critical buckling force for adaptation to our application toimplant intracortical microelectrodes into the brain. These devices offer ameans of probing the functional neuronal network activity for both basicscience and rehabilitation applicationsToincrease the critical buckling load, the mosquito reduces the effective lengthof its fascicles by using a second structure, the labium, as an insertion guide. To prevent fascicle buckling during insertion, the critical load must behigher than the penetration load. The mosquito fascicle and host tissueinterface does not perfectly follow Euler’s formula for critical buckling loadof an ideal beam due to complementary mechanisms of insertion . However, one ofthe takeaways remains true—the effective length of the implant dictates thecritical load that it can withstand without buckling.
CONCLUSION:Itis really very great experience to know about something great which is not apart of management studies but helps in taking decisions related to businessadopting new technology. Biomemtic a non credit subject gives lot informationwhich is enough for knowing a new subject rather than asking question what isit? So according to me it is different and very interesting experience for meand it should be there always for educating new aspirants in future.
