A gyro sensor is used to measure the eyelids' tilt and it uses
electromagnetic induction to receive power.
It uses
electromagnetic induction and utilizes 82% of the heat transferred to the pan unlike gas stoves which wastes 64% of heat during cooking.
In the present study, it is intended the dynamically control the mold temperature using
electromagnetic induction. This is because the temperature is probably one of the most important parameters in polymer processing.

Electromagnetic induction sensing of soil identifies constraints to the crop yields of north-eastern Australia.
Among the topics are preparing graphene by liquid phase ultrasonic exfoliation and anti-friction performance in water,
electromagnetic induction heating bonding between carbon nanotubes and metal electrodes, the ultra-precision machining of an off-axis convex ellipsoidal surface using two different accurate spiral tool paths, the miniature stress test of miniature components based on piezoresistive stress sensors test circuit, error compensation technology of a semi-strapdown MEMS inertial measurement system, and the kinematic analysis of micro end grinding assisted by ultrasonic vibration.
There are several major methods used to transfer the power without wires such as
electromagnetic induction, electromagnetic radiation and electro conduction.
