who perceived the structure and energy dynamics of ecosystems as being analogous to energy flow between components of an electrical circuit. Medical adhesives involving glue and tiny nano-hairs are being developed based on the physical structures found in the feet of geckos. Computer viruses also show similarities with biological viruses, attacking program-oriented information towards self-reproduction and dissemination. The cooling system of the Eastgate Centre building in Harare was modeled after a termite mound to achieve very efficient passive cooling. Adhesive which allows mussels to stick to rocks, piers, and boat hulls inspired bioadhesive gel for blood vessels. The field of bionics has inspired new aircraft designs which offer greater agility along with other advantages. This has been described by Geoff Spedding, Måns Rosén, and Anders Hedenström in an article in Journal of Experimental Biology. Similar statements were also made by John Videler and Eize Stamhuis in their book Avian Flight, and in the article they present in Science about LEVs. This research in bionics may also be used to create more efficient helicopters or miniature UAVs, as stated by Bret Tobalske in an article in Science about Hummingbirds. UC Berkeley as well as ESA have been working in a similar direction and created the Robofly (a miniature UAV) and the Entomopter (a UAV which can walk, crawl and fly). A bio-inspired mechanical device can generate plasma in water via cavitation using the morphological accurate snapping shrimp claw. This was described in detail by Xin Tang and David Staack in an article published in Science Advances. Specific uses of the term In medicine Bionics refers to the flow of concepts from biology to engineering and vice versa. Hence, there are two slightly different points of view regarding the meaning of the word. In medicine, bionics means the replacement or enhancement of organs or other body parts by mechanical versions. Bionic implants differ from mere prostheses by mimicking the original function very closely, or even surpassing it. The German equivalent of bionics, Bionik, always adheres to the broader meaning, in that it tries to develop engineering solutions from biological models. This approach is motivated by the fact that biological solutions will usually be optimized by evolutionary forces. While the technologies that make bionic implants possible are developing gradually, a few successful bionic devices exist, a well known one being the Australian-invented multi-channel cochlear implant (bionic ear), a device for deaf people.
