Researchers create sensor system that can ride on a moth’s back


Team Udayavani, Oct 12, 2020, 4:50 PM IST

University of Washington researchers have created a 98-milligram wireless sensor system that can ride aboard a moth and be airdropped without breaking.

Once it has landed, the sensor can be used to collect data, such as temperature or humidity, for almost three years. It is fixed on a moth using a magnetic pin surrounded by a thin coil of wire.

According to TechCrunch, To keep things lightweight and simple, the little sensor is held on with a tiny magnetic pin. A wireless signal can be sent that creates a current in a coil surrounding the pin, affecting its magnetic field and dropping the gadget.
