On page 314 of this issue, Tee et al. (3) report a Digital Tactile System («DiTact») based on a low - power flexible organic transistor circuit that transduces pressure stimuli into oscillating signals like those generated by
skin mechanoreceptors.

The scientists discovered that a class of
mechanoreceptors in the
skin that detect painful mechanical stimuli are part of a feedback circuit in which excitatory neurons that produce the hormone somatostatin are inhibited by neurons that synthesize dynorphin (a natural analgesic molecule that produces effects similar to opiates).
This tells us it's not just the
mechanoreceptors in the
skin, but receptors in the ligaments, knuckles, wrist, elbow and shoulder that could be enabling humans to sense minute differences using touch,» he added.
Yet although these advances have restored a rudimentary sense of touch, the sensors and signals are very different from those sent by
mechanoreceptors, natural touch sensors in the
skin.
Nagoya, Japan (Scicasts)-- When a fingertip explores the surface of a material,
mechanoreceptors called Meissner's corpuscles (MCs) near the surface of the
skin mainly respond to low - frequency vibration stimuli...
A
skin - inspired organic digital
mechanoreceptor.
