The Artificial Sking for the future

Hands-touching-680x355-P1060906

Summary:

  As for the technology, there is two cores part under our consideration which are organic circuits and pressure sensors. To mimic the real mechanoreceptor, the material and structure of the sensor are carefully chosen. In the research, the team has chosen carbon nanotubes moulded into pyramidal microstructures, which is highly sensitive to force stimulus by better way in tunnelling the signals from the e-field of nearby objects to the receiving electrode. For the generating mechanism, the greater force reduces the gap between the carbon nanotube and increases the flow of electricity,in order to to generated the signal more frequently which like a transformation between mechanic force with the electrical force. Apart from the sensor, the requirement of the circuit board connected the sensor must be soft and with high electrical conductivity. It is special polymer  produced by the inkjet printing from the Xerox company which allows large sheets of flexible electronics to be fabricated in new cost. Other than these, finally, to connect the signal with the brain, ontogenetic is use bridge them together which is the use of the light to control the neutron transmission.

  My opinions:

  For this technology, there are still many obstacles left behind. For the engineers, it is difficult to maintain the stability and the accuracy of the sensation. Besides, different people may has different sensory feeling. If one patient lose one hand only, it is difficult to make an artificial hand with the similar sensory feeling of the original one. Indeed, human sensation is too complicated. There are many sensation feelings, like soft feelings and hot feelings, which cannot computed easily.
