Virtual fashion show where you can buy clothes

We integrated multiple deep techs to create a virtual fashion show where real clothes can be purchased. The fashion show is semi-interactive, allowing customers to check the texture and size of clothing before ordering.
To tell the specific technologies, avatar generation, motion generation, music generation, clothing pattern creation, and fabric texture creation, all use different software, which are integrated on physical simulation software. Fabric textures are captured in high quality from real cloth using our own texture scanner.
Of course, the clothing patterns are not fictitious, but producible patterns are provided. A website for online purchasing is also available.
See also the attached video under development. Note that the fabric patterns in the video are fictitious generated by AI.

Precise bonding equipment for electronic devices utilizing heat sink laser welding

Although electronic devices and medical apparatuses require precise bonding technology for infinitesimals like micro switch or encapsulated bonding for large acreage objects like flat panel display, there are issues of influence by heat and insufficient accuracy for the products in the conventional boding methods under practical application.
The newly developed precise bonding equipment for electronic devices can solve those issues and realize welding by the surface refrigeration inside melting method using high-speed and high-performance laser in order to meet each need and each size.
This technology is the result of Adaptable and Seamless Technology Transfer Program (A-STEP) implemented by Japan Science and Technology Agency (JST) applying no-surface-damage laser welding method developed by the Advanced Laser Resin Welding Technology/Promotion Consortium.

2.45 GHz microwave oscillator and an atmospheric pressure plasma needle

The 2.45 GHz microwave oscillators produced by Plasma Applications Co., Ltd., (Research and development venture from Shizuoka University) have such properties as high-efficiency, small-scale and long-life so that they are used for a variety of applications such as long-lived plasma generation. The atmospheric pressure plasma needle developed by the laboratory has the following characteristics:
1) Simple configuration, compact and inexpensive
2) Operation at the atmospheric pressure
3) Stable temperature control
4) Low electric power consumption, achievement of AC power-less wire-less systems using the battery
5) Processing in fine areas (minimum 2 mm in diameter).
6) Environmentally friend and safety for the human body.

Development of Metal Myoelectric Hand Prothesis with Lightweight and Robust Optimal Design generated by Generative Design

We have developed a lightweight and robust metal myoelectric prosthetic hand using an optimization design tool called Generative Design. As a result, we were able to achieve the lightest weight while maintaining the robustness required for myoelectric prosthetic hands. Furthermore, by introducing a torsion spring with moving parts only in the gripping direction at the joins of the four-finger bases, the necessary pinch force (force to grasp an object) is ensured while receiving an unexpected external force.

Neural network algorithm that evaluates and outputs image quality with the same precision as human subjectivity

Up to today, the evaluation of image quality was performed by statistically processing and quantifying the subjective assessments of a large number of people, which requires many work processes. In our laboratory, we have developed an algorithm that uses neural networks to output image quality evaluation with the same precision as human subjectivity. On top of the immediate output, it is also possible to analyze image quality degradation factors such as light effects (shadows, lighting, etc.) and compression. Moreover, the technology may be applicable to video and audio quality evaluation also. For example, applications to image inspections, onboard cameras, robot vision, etc. could be possible.

Speech processing technology capable of extracting clear voice even in noisy environments with time variation

There are various noises in the everyday environment. Although noise removal technologies have advanced, it has been difficult to remove noise that has a large time change. In our laboratory, we have developed new noise reduction/removal technologies, such as in-frame processing method that works even with time-varying noise. This is effective not only for call quality such as telephone calls, but also for personal authentication and device control by voice, and is applicable not only to voice, but also to images. It can also support the use of deep learning.

Robot using artificial muscles simulating peristaltic movement of earthworms and its application to pipe inspection, high viscous fluid pumping, and excavation

Earthworms move through narrow spaces by peristaltic movements. In Nakamura group, we are developing a robot that simulates the peristaltic movement of an earthworm by using our original artificial muscles as its constituent parts which "contract and expand" by air pressure. This system does not require moving space for its direction change; it can be applied for in-pipe inspection, mixing and separation of solid-liquid mixtures, pumps for solid-liquid mixtures and high viscosity fluids for transportation of sludge, food, cement, etc., and excavation in the ground in combination with an earth auger.

The combination of measurement wavelengths can be freely selected. Multispectral camera

It's a venture company in university. We have developed a multispectral camera to extract and analyze the reflection spectrum of any (6bands) (+ RGB : 3 bands) in a wide range of wavelengths from visible to near-infrared (350 nm to 1050 nm). We can see the material properties that we couldn't see from our own spectral functions. It is cheaper than a hyper-spectral camera or an overseas multi-spectral camera. It can be applied to various uses such as inspection and analysis. We offer flexible suggestions to customers, such as equipment sales, customization, etc.

Ultra small spectrometer which is applicable to near-infrared region by using MEMS processes

We are researching a small spectrometer using MEMS processes.
The wavelength band of the object depends on design, and can be spectroscopically divided into 20 nm resolution at the near-infrared range of 1200 nm to 1500 nm, for example.
We also examine spectroscopic methods in the visible light region and in the longer wavelength region. The size of the small-scale spectrometer has some good prospect of several mm of thickness and about 1 cm wide so that it can also be installed on portable devices such as smartphones. The features are the simple manufacturing process, the cost effective, and excellent portability. We welcome anyone who is interested in realizing its practical use and joint research of this technology.
