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.
Not exact matches
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).
Inspired
by natural
mechanoreceptors, researchers led
by Zhenan Bao, a chemical engineer at Stanford University in Palo Alto, California, set out to make sensors that churn out digital signals directly.
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.
