Correction (25 August 2011): On several pages and in certain figures, the substrate material has been correctly identified as a modified silicone (not polyester) produced by Smooth-on, Easton, USA (not BASF).

Movie S1
A movie clip that illustrates the EES mounting procedure, deformations and extreme flexibility after detachment. The movie also shows an EES mounted on a commercial temporary transfer tattoo.
Movie S2
A movie clip that illustrates real-time EMG waveforms recorded from left forearm. The time horizon on the monitor is 8 s. The movie starts with 1 s of resting and is followed by 8 repetitions of grasping and opening of the left hand over the next 19 s. Each grasping lasts about 2 s and elicits the signature high-frequency oscillations of EMG, which disappears as soon as the hand opens. The measurement was done using dry, passive EES devices for all electrodeskin contacts, without any conductive gel anywhere. The stratum corneum was exfoliated with Scotch tape for recording and reference electrodes. The ground electrode was mounted on the right ankle, the reference electrode was mounted near the interior of left elbow, and the recording electrode was placed 8 cm to the anterior of the reference.
