Spermatozoa as Functional Components of Robotic Microswimmers

In recent years, the combination of synthetic micro‐ and nanomaterials with spermatozoa as functional components has led to the development of tubular and helical spermbots – microrobotic devices with potential applications in the biomedical and nanotechnological field. Here, the initial advances in this field are discussed and the use of spermatozoa as functional parts in microdevices elaborated. Besides the potential uses of these hybrid robotic microswimmers, the obstacles along the way are discussed, with suggestions for solutions of the encountered challenges also given. The initial advances in using spermatozoa as functional components in robotic microdevices are summarized giving an overview of the state‐of‐the‐art combinations of single‐spermatozoa‐carrying robotic components, as well as of their potential applications and current challenges.
