About
Marika Hayashi is a pioneering robotics researcher whose work centers on tactile sensing, soft robotics, and human-robot interaction — particularly the development of humanoid robots capable of safe, close-contact engagement with people. Her most significant contribution lies in creating "sensor flesh" systems: soft, stretchable exteriors embedded with distributed multi-axis force sensors that allow robots to perceive and respond to contact across their entire bodies. Her landmark 2009 paper on stretchable knit sensors (40 citations) addressed a critical challenge in humanoid design — enabling tactile sensitivity around flexible joint regions — while her complementary work on soft sensor exteriors (38 citations) demonstrated practical applications in nursing care and household assistance contexts. Building on earlier foundational work from 2007 (32 citations), Hayashi established a coherent research vision for robots possessing both "bone" and "flesh," transforming how the field approaches physical human-robot coexistence. Her robots, including the small humanoid "macra," served as testbeds for these innovations. With cumulative citations approaching 160 across her key publications, Hayashi's research has meaningfully shaped the trajectory of whole-body tactile sensing and safe humanoid design, making her an important voice in socially assistive robotics.
