Development of Passive Millimeter-wave Imaging Device for Practical Applications

NEXT
PREV
特徴・独自性
  • Millimeter wave (MM-wave) which is one of the electromagnetic wave transparent the clothes, the fire and the wall etc. and all natural materials including objects in clothes always radiate the electromagnetic wave as the thermal noise. Using these characteristics of MM-wave, imaging of concealed objects in clothes can be accomplished in a noninvasive and noncontact manner. This technique is called Passive Millimeter Wave (PMMW) Imaging technique and we have developed a PMMW imaging device for security applications.
  • The wave length of MM-wave frequency range is from 1 mm to 10 mm and the spatial resolution of images in MM-wave range is low compared with sub-millimeter (terahertz) range or Infra-Red range, however, higher transmittance through clothes can be obtained compared with higher frequency range. Furthermore, low noise amplifier (LNA) exists which could be the advantage of MM-wave compared with higher frequency ranges.
  • Now the device was developed for the purpose of keeping safe and secure aircrafts and ships etc., we hope to conduct collaborative research with a willing company for a practical application of this technology in industrial fields such as the fire rescue, the police equipment and the medical devices.

Novel CoCr-based superelastic metallic biomaterial with low Young's modulus

NEXT
PREV
特徴・独自性
  • General metallic biomaterials, such as stainless steels and conventional CoCr alloys, show a high Young's modulus ten times higher than that of human bones. This is an unfavored feature because it causes the so-called "stress shielding effect" when they are used as implants. β-type Ti alloys have a relatively lower Young's modulus, but they come with a compromise of low wear resistance. The current novel CoCr-based alloys are a breakthrough; they exhibit both a low Young's modulus similar to human bones and a high wear and corrosion resistance. Moreover, they exhibit superelasticity with a huge recoverable strain over 17%, also showing promise as shape memory alloys.
実用化イメージ

It is the first time that a low Young's modulus, a high corrosion and wear resistance, and a superior superelastic behavior are simultaneously obtained in a single material. The current novel CoCr-based alloys are promising for biomedical applications such as total hip or knee joint replacements, bone plates, spinal fixation devices, and vascular stents.

A novel crystal growth via controlling an energy relationship between crystal and melt with applying an electric field

NEXT
PREV
特徴・独自性
  • This lab is concerned with the novel approach mainly for the growth from melt by studying the relationship between the interface dynamics during growth and properties of grown crystals. Special interests lie in the growth of new crystals via the imposition of an interface-electric field. Nano-scaled control of crystal growth is executed in an electric double layer of ~nm thickness that is induced by applying an external electric field on the growth interface. Some of our growth results brought by applying an electric field are;
  • 1. Growth of Langasite-type crystals for the pressure sensor at high temperature by manipulating the energy relationship between crystal and melt.
  • 2. Easy nucleation of protein crystals that are normally hard to crystallize.
  • 3. Formation of Si crystals with desired structure by manipulating the interface instability of Si.
  • Crystals developed this way will widen an opportunity to collaborate with industries in the field of the piezoelectric, magnetic, optic and other fields related to the highly-networked information society.
