  • Force sensor
    Patent number: 11971315
    Abstract: Disclosed is a force sensor. More particularly, the force sensor includes a first permanent magnet layer; a magnetic tunnel junction disposed on the first permanent magnet layer and configured to have a preset resistance value; and a second permanent magnet layer disposed to be spaced apart from the magnetic tunnel junction, wherein the second permanent magnet layer moves in a direction of the first permanent magnet layer when pressure is applied from outside, the preset resistance value of the magnetic tunnel junction is changed when a magnetic field strength formed between the first permanent magnet layer and the second permanent magnet layer becomes a preset strength or more according to movement of the second permanent magnet layer, and the force sensor senses the pressure based on a change in the preset resistance value.

  • Method for preparing D-chiro-inositol using microbes
    Patent number: 9725739
    Abstract: The present invention relates to a method for preparing D-chiro-inositol from myo-inositol by using a transformed host cell which expresses enzymes such as a myo-inositol transporter, inositol dehydrogenase, and inosose isomerase. According to the method of the present invention, myo-inositol can be converted into D-chiro-inositol at a high yield.
