仿生學是一門既古老又年輕的學科，是以自然為靈感，解決地球上人類面臨的問題的一個分支。人們研究生物體的結構與功能的工作原理，并根據這些原理發(fā)明出新的設備、工具和科技，創(chuàng)造出適用于生產、學習和生活的先進技術。
仿生學一詞是1960年由美國斯蒂爾根據拉丁文構成Binics一詞，后來演變成Bimimetics。1997年Janine Benyus首次提出Bimimicry一詞。某些生物具有的功能迄今比任何人工制造的機械都優(yōu)越得多，仿生學就是要在工程上實現并有效地應用生物功能的一門學科。例如關于信息接受(感覺功能)、信息傳遞(神經功能)、自動控制系統(tǒng)等，這種生物體的結構與功能在機械設計方面給了很大啟發(fā)。
仿生學的例子有很多，如將海豚的體形或皮膚結構(游泳時能使身體表面不產生紊流)應用到潛艇設計原理上。又比如，蒼蠅是細菌的傳播者，一般歸類為害蟲，可是蒼蠅的楫翅是天然導航儀。而且，它的眼睛是一種“復眼”，由3000 多只小眼組成，人們模仿它制成了“蠅眼透鏡”。“蠅眼透鏡”是用幾百或者幾千塊小透鏡整齊排列組合而成的，用它作鏡頭可以制成“蠅眼照相機”，一次就能照出千百張相同的相片。這種照相機已經用于印刷制版和大量復制電子計算機的微小電路，大大提高了工效和質量。
仿生學也被認為是與控制論有密切關系的一門學科，而控制論主要是將生命現象和機械原理加以比較，進行研究和解釋的一門學科。

華佗在《莊子》“二禽戲”(“熊經鳥伸”)的基礎上創(chuàng)編了“五禽戲”。其名稱及功效據《后漢書·方術列傳·華佗傳》記載:“吾有一術，名五禽之戲：一曰虎，二曰鹿，三曰熊，四曰猿，五曰鳥。亦以除疾，兼利蹄足，以當導引。體有不快，起作一禽之戲，怡而汗出，因以著粉，身體輕便而欲食。普施行之，年九十余，耳目聰明，齒牙完堅?！?br>南北朝時陶弘景在其《養(yǎng)性延命錄》中有比較詳細的記載：“虎戲者，四肢距地，前三擲，卻二擲，長引腰，側腳仰天，即返距行，前、卻各七過也。鹿戲者，四肢距地，引項反顧，左三右二，左右伸腳，伸縮亦三亦二也。熊戲者，正仰以兩手抱膝下，舉頭，左僻地七，右亦七，蹲地，以手左右托地。猿戲者，攀物自懸，伸縮身體，上下一七，以腳拘物自懸，左右七，手鉤卻立，按頭各七。鳥戲者，雙立手，翹一足，伸兩臂，揚眉鼓力，各二七，坐伸腳，手挽足距各七，縮伸二臂各七也。夫五禽戲法，任力為之，以汗出為度，有汗以粉涂身，消谷食，益氣力，除百病，能存行之者，必得延年”。陶弘景在該書中，不但對五禽戲的具體操作步驟進行了描繪，而且提出了五禽戲的鍛煉原則——“任力為之，以汗出為度”。
