"Sensors that monitor infrastructure, such as bridges or buildings, or are
used in medical devices, such as prostheses for the deaf, require a
constant supply of power. The energy for this usually comes from
batteries, which are replaced as soon as they are empty. This creates a
huge waste problem. An EU study forecasts that in 2025, 78 million
batteries will end up in the rubbish
every day.
A new type of mechanical sensor, developed by researchers led by Marc
Serra-Garcia and ETH geophysics professor Johan Robertsson, could now
provide a remedy. Its creators have already applied for a patent for their
invention and have now presented the principle in the journal
Advanced
Functional Materials."
