Researchers at ETH Zurich have structured a wafer-thin silicon membrane in such a manner that it can direct mechanical waves along specific paths. Such structures offer interesting opportunities for converting unwanted vibrations into usable energy or for processing mechanical signals.
Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages.
What if students were free to pursue their ideas without any pressure? That is precisely the approach that the ETH Student Project House has taken for the past decade. Director Lucie Rejman tells us about the results.
