Ali Hajimiri Awarded $6 Million to Develop Self-Healing Circuits

Over the past few decades, the transistors in computer chips have become progressively smaller and faster, allowing upwards of a billion individual transistors to be packed into a single circuit, thus shrinking the size of electronic devices. But these circuits have an intractable design flaw: if just a single transistor fails, the entire circuit also fails. One novel way around the problem is a so-called self-healing circuit. Such circuits are "inspired by biological systems that constantly heal themselves in the presence of random and intentional failures," says Caltech professor Ali Hajimiri.
