"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
