Biomimetics Progress Report
Biomimetics in 2022: An Academic Progress Report
Post: 2023-06-20 17:18  View:1031

For this report, Thomson Reuters Web of Science Database (WoS) was taken as the source of publications. Data were tracked during April of 2023 to retrieve publications of the year 2022. Topic including the title, abstract and keywords were selected as the searching fields. Keywords tracked included biomimicry, biomimetic, biomimetics, biomimic, bio-inspired, bioinspired, bionic, nature-inspired, biologically inspired, bioinspiration, bio-inspiration, and biomimicking. The rankings of different countries/regions, universities, authors, journals and research areas were generated based on the final number of published papers. 

General

The total number of research papers retrieved in 2022 was 10,581 with 165 highly cited papers and 21 hot papers. The growth trend indicated that biomimetic research has got a boost in 2022 with a growth rate of about 7.83 % (Table 1). The terminology “biomimetic” has always been the most commonly used keyword in the field, while the keywords biomimic, bio-inspiration, and biomimicking were seldom used.

Authors Distribution

The bibliometric software of CiteSpace was used to analyze the authors distribution in the field of biomimetics in 2022 based on the WoS Core Collection. The software could not accurately distinguish the affiliations to which the authors belong, resulting in the unexpected publication accumulation of different authors with the same initials. After carefully identification and verification, the top 10 core authors in the field in 2022 had been obtained as showed in Table 4.

Journals Distribution

Based on the statistics of source titles, the top 20 journals were shown in Table 5. It can be seen that in recent years more and more biomimetic achievements have been published in the high-level journals such as Chemical Engineering Journal, Advanced Functional Materials, and Advanced Materials etc., indicating that bimimetic research has received more and more attention from academic fields. Currently, there are 10 professional journals in total in the field of biomimetics, and 8 of them have been already included in the WoS (Table 6).

Areas Distribution

In 2022, 140 research areas defined by the WoS are involved in biomimetic research, and mainly distributed in the fields of engineering, materials science, chemistry, science and technology-other topics (Table 7). Biomimetics is a highly interdisciplinary domain, and its research methods involve most of the disciplines of science and engineering. Therefore, it is of great significance to promote multidisciplinary intersection and accelerate the development of biomimetics.

Conclusion

The increasing number of biomimetic research papers included by WoS indicated that the global biomimetic research activities have been steadily increasing since in recent years, and the countries and universities engaged in biomimetic research have also been on the rise. As a hotspot in scientific research in the new century, biomimetics has been attracting extensive attention of more countries and scholars and will play an increasingly important role in industrial and agricultural production, scientific and technological development, and national defense construction.
