仿生学是一门既古老又年轻的学科，是以自然为灵感，解决地球上人类面临的问题的一个分支。人们研究生物体的结构与功能的工作原理，并根据这些原理发明出新的设备、工具和科技，创造出适用于生产、学习和生活的先进技术。
仿生学一词是1960年由美国斯蒂尔根据拉丁文构成Binics一词，后来演变成Bimimetics。1997年Janine Benyus首次提出Bimimicry一词。某些生物具有的功能迄今比任何人工制造的机械都优越得多，仿生学就是要在工程上实现并有效地应用生物功能的一门学科。例如关于信息接受(感觉功能)、信息传递(神经功能)、自动控制系统等，这种生物体的结构与功能在机械设计方面给了很大启发。
仿生学的例子有很多，如将海豚的体形或皮肤结构(游泳时能使身体表面不产生紊流)应用到潜艇设计原理上。又比如，苍蝇是细菌的传播者，一般归类为害虫，可是苍蝇的楫翅是天然导航仪。而且，它的眼睛是一种“复眼”，由3000 多只小眼组成，人们模仿它制成了“蝇眼透镜”。“蝇眼透镜”是用几百或者几千块小透镜整齐排列组合而成的，用它作镜头可以制成“蝇眼照相机”，一次就能照出千百张相同的相片。这种照相机已经用于印刷制版和大量复制电子计算机的微小电路，大大提高了工效和质量。
仿生学也被认为是与控制论有密切关系的一门学科，而控制论主要是将生命现象和机械原理加以比较，进行研究和解释的一门学科。

华佗在《庄子》“二禽戏”(“熊经鸟伸”)的基础上创编了“五禽戏”。其名称及功效据《后汉书·方术列传·华佗传》记载:“吾有一术，名五禽之戏：一曰虎，二曰鹿，三曰熊，四曰猿，五曰鸟。亦以除疾，兼利蹄足，以当导引。体有不快，起作一禽之戏，怡而汗出，因以着粉，身体轻便而欲食。普施行之，年九十余，耳目聪明，齿牙完坚。”
南北朝时陶弘景在其《养性延命录》中有比较详细的记载：“虎戏者，四肢距地，前三掷，却二掷，长引腰，侧脚仰天，即返距行，前、却各七过也。鹿戏者，四肢距地，引项反顾，左三右二，左右伸脚，伸缩亦三亦二也。熊戏者，正仰以两手抱膝下，举头，左僻地七，右亦七，蹲地，以手左右托地。猿戏者，攀物自悬，伸缩身体，上下一七，以脚拘物自悬，左右七，手钩却立，按头各七。鸟戏者，双立手，翘一足，伸两臂，扬眉鼓力，各二七，坐伸脚，手挽足距各七，缩伸二臂各七也。夫五禽戏法，任力为之，以汗出为度，有汗以粉涂身，消谷食，益气力，除百病，能存行之者，必得延年”。陶弘景在该书中，不但对五禽戏的具体操作步骤进行了描绘，而且提出了五禽戏的锻炼原则——“任力为之，以汗出为度”。
