Claim 16:
17. A method for producing a micro tactility-simulating sensing device, comprising the following steps:
providing a chip having a first top surface and a first inductor, wherein:
when the first top surface has wiring through holes configured to allow an external circuit to connect to the first inductor, the first top surface is a flat surface except the wiring through holes; and
when the first top surface is free from any wiring through hole, the first top surface is a flat surface;

providing a bonding wire having a first end;
connecting the first inductor to the first end of the bonding wire;
using a polymer to encapsulate the chip;
providing a magnetic rigid body; and
disposing the magnetic rigid body on the polymer, wherein the magnetic rigid body is coupled with the first inductor to allow the first inductor to sense a magnetic flux passing therethrough, the polymer has a characteristic distance between the chip and the magnetic rigid body, and the characteristic distance and the magnetic flux have a functional relationship.
