Abstract

Nature provides many examples of organisms capable of attaching themselves to other organisms. Seeds and some parasitic insects, for example, have attachment mechanisms that allow them to remain undetected for long periods of time. Such properties may be useful in military and law enforcement tagging situations, where one desires the discrete placement of an active or passive device on an unwitting host. This paper describes the development of 3D micro-scale burrs, that can readily attach to clothing, and are capable of opening the door to new methods of tracking. With the development of bulk micro-machining techniques such as LIGA and MEMS the ability to develop such a carrier taggent has arisen. 3D micro-scale burrs, made of electrodeposited nickel, have been developed using the LIGA process and have been tested for use as carriers for micro- sensors and emitters both active and passive.
