In this reference design, a strain sensor and the ML7660-EVK-002 are attached to the shaft. It is now possible to directly measure and collect data on the strain of the rotating shaft, which was previously impossible.

Specifically, the measurement process follows these steps:
1) The power supply LSI wirelessly supplies power to the power receiving LSI.
2) The power receiving LSI supplies power to the strain sensor via a wired connection.
3) The strain sensor measures the strain of the rotating shaft.
4) The strain sensor sends the strain measurement data to the power receiving LSI via a wired connection.
5) The power receiving LSI wirelessly transmits the measurement data to the power supply LSI.

This reference design uses the STREAL SR300 sensor manufactured by Glosel. If you plan to use Glosel sensors, please check directly with Glosel for availability and procurement details in advance.
