Gentle touch : Mechanoresponsive polyelectrolyte brushes show a strong correlation between local fluorescence intensity and local pressures (see picture; PDMS=polydimethylsiloxane). The response of the surface to mechanical stimuli was completely reversible and provided a sensitivity under 10 kPa, similar to human skin.
