I would call them tactile qualia. Tactile means relating to the sense of touch, and qualia is a more general term for what you are asking that is not limited to the sense of touch, but could also be a smell, or a sight, or etc.
If you absolutely need a single word, I think the term qualia expresses the most important aspects of what you are after.
Qualia is a term used in philosophy to refer to individual instances of conscious experience. The term derives from a Latin word meaning for "what sort" or "what kind." Examples of qualia are the pain of a headache, the taste of wine, or the perceived redness of an evening sky.
Daniel Dennett identifies four properties that are commonly ascribed to qualia:
- ineffable; that is, they cannot be communicated, or apprehended by
any other means than direct experience.
- intrinsic; that is, they are
non-relational properties, which do not change depending on the
experience's relation to other things.
private; that is, all
interpersonal comparisons of qualia are systematically impossible.
directly or immediately apprehensible in consciousness; that is, to
experience a quale is to know one experiences a quale, and to know
all there is to know about that quale.
