Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters found in phones and other wireless devices. They eliminate or enhance specific input signals to get the best output signals. While essential, these filters take up space on the chips that researchers are constantly trying to make smaller.
