Yu Lab
Machine-translated · View original
A robotics lab that supports rehabilitation and care at home.

AboutAbout the lab
Rehabilitation and care that can continue at home.
The Yu Lab researches and develops fundamental robotics technologies that can be applied to home-based rehabilitation and care support.
Research is carried out in three groups: biomonitoring, electrophysiological simulation, and soft robotics.
Because the lab approaches the fields of medicine, nursing care, and welfare with a variety of technologies, students can acquire a broad range of knowledge and skills through their research.
The lab hosts many international students and has active joint projects with labs overseas. Lab visits are accepted at any time.
Key terms
- Soft robot
- A robot made of soft materials such as silicone, which is less likely to injure people when it touches them
- Ballistocardiogram
- A signal that captures the tiny vibrations of the body produced when the heart pumps out blood
- Transcutaneous electrical stimulation
- A treatment method that relieves pain by passing a weak electric current through the skin
ResearchResearch themes
The lab researches fundamental robotics technologies that can be applied to home-based rehabilitation and care support. It has three groups: biomonitoring, electrophysiological simulation, and soft robotics, and multiple groups sometimes work together on a single theme.
*Illustrative imageBiomonitoring
This group works on methods for measuring biosignals without touching the body, predicting urination, and monitoring robots for home use. It is also researching the measurement of the vibrations produced when the heart pumps out blood (ballistocardiogram) using sheet-type pressure sensors that can be embedded in chairs and beds.
*Illustrative imageElectrophysiological simulation
This group uses computation to reproduce how electricity travels through the body. For transcutaneous electrical stimulation, which relieves chronic pain without drugs, it is developing methods to find the optimal waveform and to adapt it to individual differences in tissue thickness.
*Illustrative imageSoft robotics
This group handles the control and simulation of robots made of soft materials. Applications include rehabilitation gloves for the hand and fingers, meal assistance, actuators for minimally invasive surgery, and pneumatically driven nursing care robots.
*Illustrative imageMeasuring the electrical properties of tissue with MRI
This is an imaging method (MREPT) that uses an MRI scanner to examine, without harming the body, how easily tissue conducts electricity and its permittivity. Because cancerous tissue differs from healthy tissue in its electrical properties, the lab aims to tell them apart by this difference, and proposes improvements to the numerical computation as well as the use of neural networks.
