4 of the 5 senses explicitly have berachos:
Taste- Shehakol food, blessings on fruits & vegetables etc (see: OC 202-207)
Smell- Pleasant fragrances (OC 216)
Hearing- Thunder (MB 227:5)
Touch - ??
The closest I could think of would be "taking of the lulav etc" (OC 651:1)-- but that's taking, one wouldn't fulfill their obligation if they just touched a lulav.
Are there any berachos for touching something?
