ThermoScratch

Inventing New Sensations.

Temperature, touch, and bodily responses. Researchers from different universities have come together to study technologies that change, convey, and measure how people feel, and we turn that work into products and experiences.

Technology

Technology areas

To create, convey and measure new sensations, we develop products based on cutting-edge research.

Changing sensation

By combining temperatures, we change the sensation of touch on the skin itself. We turn research on thermal illusions into products.

Conveying sensation

We deliver sensations that are hard to put into words as experiences. They give people a chance to notice that what they feel differs from what others feel.

Measuring sensation

We quantify how people feel. Based on quantitative data rather than vague indicators, we help develop comfortable work environments, clothing, and more.

Each one is a real product that grew out of knowledge gained in the lab.

ThermoScratch

Thermal-illusion device

Pressing a warm surface and a cool surface against the skin at the same time can create a sensation like being scratched. We turned this “thermal grill illusion,” known in neuroscience, into a product with plates that carefully control warm and cool. It is a tool for shifting your attention away from a bothersome spot without harming the skin.

In our crowdfunding campaign on Kibidango, we raised 11.07 million yen against a goal of 2 million yen (the campaign ended on September 29, 2026). After the campaign, we plan to focus on sales to businesses and specialist institutions.

This is a general consumer product for refreshing everyday discomfort, not a medical device. Sensations vary from person to person.

How it works
Presents warm (38-45°C) and cool (10-20°C) at the same time. Stops automatically after about 15 seconds
Size
About 227 x 44 x 42 mm / about 320 g / USB-C charging
Intellectual property
Patent No. 7113586 on Peltier elements
Development
About 5 years from research to product

Conveying sensation

Perionoid

Menstrual-pain VR experience device

The Perionoid unit and electrode pads
The Perionoid unit and electrode pads (from the official video)

Understanding another person’s pain and telling others about your own are both difficult. Perionoid is a device that uses electrical muscle stimulation (EMS) to let people experience lower abdominal menstrual pain in stages. Starting from a device born from research at Konan University and Nara Women’s University, we simplified the controls and improved it so it can be worn.

Given the same experience, some people feel strong pain and others feel none at all. Noticing that difference is a way into thinking about what other people feel.

The experience is for volunteers only. It is conducted with staff present, after an explanation and written consent, starting with weak stimulation, and in a way that lets participants stop at any time by their own choice. We do not accept people with health concerns. The pain you experience is only a small part of menstrual symptoms.

Where it is used
In-house corporate training, exhibitions at academic conferences, media coverage, and more
Training inquiries
Training for companies, educational institutions, and local governments is handled by our contractor, Linkage Inc.

SenseChair

Seated body-sway measurement device

Two people sitting face to face on SenseChairs
Two people in conversation
Side view of a person sitting on a SenseChair
It looks like an ordinary office chair
Screen showing measurement waveforms from several SenseChairs side by side
Measurement data from several chairs (from our materials)

This chair-shaped instrument records the load and center-of-pressure sway of the person sitting, using high-precision strain sensors built into the seat. There is nothing to wear and nothing to operate. With several chairs, it can also show how closely people’s body movements synchronize in meetings and conversations.

What is measured is body movement and response. This is not a device that directly reads the sensations or emotions of the person sitting.

Data obtained
Center-of-pressure coordinates (X, Y) and load. With multiple chairs, the tendency of body movements to synchronize
Where it is used
Research in education, medicine, nursing care and rehabilitation, ergonomics and behavioral science, and psychology and social behavior
Specifications
Max load 130 kg / 16-bit / about W45 x D45 x H80 cm / about 12 kg / USB and Bluetooth / CSV output
Customization
Custom versions of the dedicated analysis software are available

Measuring sensation

ThermoFeel p

Handheld contact warm/cool feeling tester

The ThermoFeel p unit, a handheld device with a display and a grip

This tester lets you compare, in numbers, how cool or warm a material feels to the touch. Conventional benchtop testers require a sample to be cut out and measured in a constant-temperature, constant-humidity room. ThermoFeel p is held in the hand and measures furniture, interior materials, and other items as they are, in the place where they actually sit. You operate it simply by following the on-screen instructions.

What is measured is a physical quantity: how much heat moves from a material. When people touch something cold, heat moves and it feels cool. This device evaluates how cool (or warm) something feels from the amount of that heat movement.

How you feel changes with rhythm.

Choose an experience, then tap the circle in the middle. A low rhythm and rippling visuals start together. Sound will play, so please mind your volume.

Type of experience

Tap the circle to start the sound and visuals.

About this experience.This small demo uses a low-pitched rhythm and moving visuals to show that the same stimulus can feel different. Overtones are layered on the low tones so they can be heard even on a smartphone's small speaker. It does not reproduce the thermal or tactile sensations our products create.
