The humanoids I'm talking about are designed with all the characteristics pertaining to robots developed with the help of soft robotics technologies. Although the skeleton is made of titanium, their "muscles" are produced from soft multi-material actuators. There's a network of nanosensors forming a substitute to human sensory receptors.
The only thing I haven't yet come up with are heating elements, which will give warmth of a normal human body and at the same time won't melt delicate synthetic materials. Can anyone give a clue what sort of material can be used here? Can it be an alternative of human vascular system (as my humanoids can work on biobatteries, so this energy can be distributed by "vessels")?
The warmth is a key feature for humanoids in my world, because they work with humans and sometimes for humans providing elder care services or medical care.
