tracking sensors

The low-cost sensor is about the size of a button-cell watch battery

A new system uses RFID tags to home in on targets, which could benefit robotic manufacturing, collaborative drones, and other applications

Wireless real-time monitoring could add precision to the linkage between diet and health

A recent study shows that by tearing tissue paper that’s loaded with nanocomposites and breaking the paper’s fibers, the paper acts as a sensor

Birds that yield good vibration provide motion excitation ... for engineers: As Earth warms, birds may be changing their migratory patterns. But to obtain avian data, scientists need in-flight tracking sensors – and those sensors need energy.

System enables monitoring, tracking and securing of nuclear material.
