Abstract: Disclosed are porous multi-metal oxide nanotubes and a production method therefor. In one aspect, methods for producing porous multi-metal oxide nanotubes are provided comprising: (a) preparing an admixture comprising metal-acetylacetonate precursors, polyacrylonitrile (PAN) and a solvent component; and (b) producing a nanocomposite from the admixture, wherein metals of the metal-acetylacetonate precursors comprise a non-radioactive alkali metal stable isotope and a non-radioactive alkaline earth metal stable isotope. As such, porous multi-metal oxide nanotubes having a single-phase multivalence may be obtained in high yield without using harmful chemical substances. In addition, the polymer electrolyte membrane including the porous multi-metal oxide nanotubes may have maintained and improved mechanical strength, and thus may have maintained durability even during cell operation and may also have improved proton conductivity even at low humidity. The fuel cell including the polymer electrolyte membrane may have improved performance.

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.
