Abstract
<p class="first" id="P1">Untethered robots miniaturized to the length scale of millimeter
and below attract
growing attention for the prospect of transforming many aspects of health care and
bioengineering. As the robot size goes down to the order of a single cell, previously
inaccessible body sites would become available for high-resolution
<i>in situ</i> and
<i>in vivo</i> manipulations. This unprecedented direct access would enable an extensive
range of
minimally invasive medical operations. Here, we provide a comprehensive review of
the current advances in biome dical untethered mobile milli/microrobots. We put a
special emphasis on the potential impacts of biomedical microrobots in the near future.
Finally, we discuss the existing challenges and emerging concepts associated with
designing such a miniaturized robot for operation inside a biological environment
for biomedical applications.
