A team of researchers from the University of Ottawa has developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential ...

Anybody can develop high frequency hearing loss, but it becomes more common with age. Exposure to loud sounds or high frequency sounds are common causes of ear damage in younger people.

The circuit modulates the incremental change in the sensor resistance in the form of a change in the frequency of the relaxation oscillator. The baseline resistance of the sensor is automatically ...
