Scientists have developed a Fitbit water quality detector that tracks mussel activity.
When the mussels
In the new system, the developers observe the behavior of the mussels to determine how often the mussels are closedtheir shells, at what speed and how they coordinate with each other.
Specifically, the system uses two inertial units (IMUs) on each mussel.Each of the IMUS includes magnetometers and accelerometers: they are probably in your smartphone and monitormoving it from place to place.
One IMU is attached to the upper shell of the mussel, the other to the lower shell.This allows researchers to compare the movement of the shell halves relative to each other.In other words, it allows researchers to determine whether the mussel is accurately coveringhis shell.
When placed in a natural environment, the systemdata collection is powered by a solar panel and transmits data from sensors wirelessly. The developed type works for four mussels connected to the system, but can handle dozens.
