Research Project

Project/Area Number	19K14948
Research Institution	Waseda University
Principal Investigator	Somlor Sophon 早稲田大学, 理工学術院総合研究所(理工学研究所), 次席研究員(研究院講師) (40791231)
Project Period (FY)	2019-04-01 – 2022-03-31
Keywords	Tactile sensor
Outline of Annual Research Achievements	This year, we explored the possibility of a new type of tactile sensor. This sensor has a capability of sensing both proximity and force using just Capacitive-based transducer. This sensor can be used for safety of human-robot interaction. Furthermore, we also further improve a Hall-effect based tactile sensor on human's finger. The sensor can measure 3-axis force that a wearer applied when touching an object with fingers. The obvious feature of this sensor is that the sensor doesn't obstruct the touching of the fingers like usual glove-type sensor does.
Current Status of Research Progress	Current Status of Research Progress 2: Research has progressed on the whole more than it was originally planned. Reason The research progress smoothly even though there are some changes of plans such as the development of a new sensor.
Strategy for Future Research Activity	We will continue the development of both the capacitive-type force-proximity tactile sensor for robot safety and the Hall-effect tactile sensor for human.
Causes of Carryover	To further develop the sensors.
