Mimicking nature – from technological know-how fiction to engineering reality

Humans have continually appeared to nature’s innovations as a resource of concept. The remark of flying birds and bugs ends up in strategies in aeronautics. Collision avoidance sensors mimic the whiskers of rodents. Optimization algorithms are in line with survival of the fittest, the seed-picking strategy of pigeons, or the habit of ant colonies. in recent times those efforts became extra in depth, with researchers looking principles, strategies, and rules of biology to encourage new chances in fabrics, mechanisms, algorithms, and fabrication methods. A overview of the present country of the art, Biomimetics: Nature dependent Innovation records key organic ideas that offer a version for ideas in engineering and technological know-how.

Leading specialists handle quite a lot of themes, together with:

  • Artificial senses and organs
  • Mimicry on the cell–materials interface
  • Multiscale modeling of plant phone wall structure and tissue mechanics
  • The making of biomimetic composites
  • Electroactive polymer (EAP) actuators as man made muscles
  • EAP-based refreshable braille displays
  • Biomimetic optics from the angles of biology and plants
  • Biomimicry of flying birds, bugs, and marine biology
  • Applications of biomimetics in production, items, and medicine
  • Robotics, together with the advance of human-like robots
  • Biologically encouraged layout as a device for interdisciplinary education
  • The biomimetic strategy in creative creation

The ultimate bankruptcy outlines the demanding situations to biomimetic-related innovation and provides a imaginative and prescient for the future.

A follow-up to Biomimetics: Biologically encouraged Technologies (2005), this accomplished reference methodically surveys the most recent advances during this swiftly rising box. It positive factors an abundance of illustrations, together with a 32-page full-color insert, and gives huge references for engineers and scientists attracted to delving deeper into the examine of biomimetics.

Regardless of the ever-present value of medication in Roman literature, philosophy, and social historical past, the language of Latin scientific texts has now not been accurately studied. This e-book offers the 1st systematic account of part of this huge, wealthy box. focusing on texts of "high" medication written in trained, even literary, Latin Langslow bargains an in depth linguistic profile of the clinical terminology of Celsus and Scribonius Largus (first century advert) and Theodorus Priscianus and Cassius Felix (fifth century AD), with common comparisons with their respective near-contemporaries.

Ectogenesis: Artificial Womb Technology and the Future of Human Reproduction (Value Inquiry Book Series 184)

This e-book increases many ethical, felony, social, and political, questions concerning attainable improvement, within the close to destiny, of a man-made womb for human use. Is ectogenesis ever morally permissible? if this is the case, lower than what situations? Will ectogenesis improve or decrease women's reproductive rights and/or their monetary possibilities?

16 Biomimetics: Nature-Based Innovation Sensors are widely used, and no system can be imagined to operate effectively without them. Pressure, temperature, and optical and acoustical sensors are used and are being improved continuously in terms of their sensing capability while reducing their size and consumed power. The eye is mimicked by the camera (with air rather than the fovea aqueous content), the whiskers of rodents are mimicked as collision avoidance sensors, and the acoustic detectors imitate the sonar in bats.

Even babies are now found in many stores. Also, higher-end robots and toys are becoming increasingly sophisticated, allowing them to walk and even converse with humans using a vocabulary at the level of hundreds of words (Chapter 16). Some robots can be operated autonomously or remotely reprogrammed to change their characteristic behavior. One of the first robots that was able to converse and react to human expressions, both facially and verbally, is the Kismet, which was developed at the Massachusetts Institute of Technology (Breazeal, 2002; Bar-Cohen and Breazeal, 2003).

The actuators that are the closest to mimic natural muscles are the electroactive polymers (EAPs), and for this characteristic, they gained the name “artificial muscles” (Bar-Cohen, 2004; Chapter 6). There are many types of EAP materials that are known today, and most of them have 17 Introduction: Nature as a Source of Inspiring Innovation emerged in the 1990s. Unfortunately, these materials are still limited in their ability to generate sufficient forces to perform significant tasks such as lifting heavy objects.
