 This is my grandmother. She is 105 years old. And my granddaughter was born three months ago. So in my family, the fifth generation are very active. Thank you. This is a very extreme case, however. Our planet population is aging rapidly. By 2030, 34 countries are super-aged. So we need to find a way to realize self-empowerment society where the people are woke and study continuously. But the report of the WHO said over 35 million people have a dementia and it will be doubled by 2030 with this estimation, one of the fifth people with dementia in the future. So in order to tackle this problem, we developed the sensor to monitor the dementia and related brain activities. And ideally, the sensor can be used at home or office instead of the hospital where the limited access. Currently, the sensor is like this, using the MRI and MEC stone here. Immediately, you can see it's large and highly portable. It requires ultra-low temperature to operate the superconducting sensor. And it is very expensive. Let me introduce a simple solution using diamond. By changing the structure slightly, we can transfer them from the beautiful object jewelry to quantum sensors. And the quantum sensor can be operated at room temperature. So diamond consists of all carbon atoms. If the carbon is removed and replaced with nitrogen, and we produce nitrogen vacancy center, so we can arrange the special arrangement of the electron state. And the electron spins property can monitor the magnetic field. And we use the quantum mechanical property of the electron spin. And quantum manipulation allows us to detect the very small signal of the magnetic field, like a neuron activity. But how do you make the diamond? Natural diamonds are produced deep inside the earth, but we can obtain the diamond in my lab. We combine the microwave, just like your kitchen, and with mesangas, so we can make it. And this atomic-scale sensor possibility to spatial application from DNA, protein, cell, and heart and brain monitoring. This sensor is a future candidate of the Internet of Nano-Things. So a future brain imaging, that sensors are arrayed onto the head. It has the possibility to real-time monitoring by big data analysis shown, Professor Takayasu. And it is very important to develop the supercomputer. And automatic driving systems are quickly advancing. My medical application is a detection of the brain cancer. Spray it in the lymph node. Currently, their surgery is removed, so the non-inverse detection is demanded. So we are developing by using the diamond sensor to detect the brain cancer. So I see the diamond is a future candidate of the Internet of Nano-Things. They can collect data, portably, in the expressively and non-investably at a room temperature. And when to collect the Internet of Nano-Things, the diamond sensor will have a possibility to impact of the self-enforment society. And I would like to discuss you about how this sensor and Internet things to apply for the aging planet. And I hope you are interested in the diamond sensor. Thank you.
