Neurelectronics were delicate circuits used on robots and cymeks that allowed them to "feel". Some robots like Erasmus had a skin of organic-plastic composites laced with a sophisticated sensor network of neurelectronics. Erasmus had designed an adjustable a sensory-enhancement module grafted by neurelectronic ports onto his body core which allowed Erasmus to simulate the senses of humans. He always wanted to know and feel more than the module could provide.
