Purpose – This paper aims to provide an insight into recent biomimetic sensor developments. Design/methodology/approach – Following a brief introduction, this paper considers a number of specific sensor R&D activities which involve the use of differing biomimetic concepts, including the fabrication of artificial sensing organs, emulating human senses, novel uses of biological structures and systems exploiting biologically-inspired behaviour. Findings – This paper shows that a range of different biomimetic design concepts are being applied to sensors that respond to a range of physical, gaseous and chemical variables. Robust, multi-sensor systems are being developed which emulate biologically-inspired behaviour. Originality/value – This paper provides an up to date technical review of a range of differing biomimetic sensor designs and concepts.
