D'Arsonval Movement-Based Precise Milligram Force Control for Individual Touch Sense Assessment.

Humans cannot feel the contact (or touching) force when it is too weak and falls in a specific range. For instance, if it is between several dozens and hundreds of milligram force, then humans may not be able to distinguish whether the object has come in contact with their skin or not. The minimum contact force that the human can feel is called the light touch threshold (LTT). This paper presents ...
