Everyone learns in school that man have five basic gage : touch , sight , hearing , taste , and smell . There are actuallyseveral more , but one that world do n’t inherently have is magnetoception , the ability to comprehend magnetic field . This sense can be find in certain bacterium , migrant dame , Pisces , and invertebrates , and provides a better sense of navigation and predilection . A Modern newspaper published inNature Communicationsby lead author Michael Melzer of the Leibniz Institute for Solid State and Materials Research in Dresden , Germany distinguish a new electronic pelt , which provides a “ sense ” of magnetic fields that will have a wealthiness of implications when it is developed further .
" We have march an on - skin skin senses - less human - machine fundamental interaction political platform , apparent motion and displacement reaction sensorics applicable for sonant robots or functional medical implants as well as charismatic functionalities for electronics on the skin , " Melzer articulate in apress release .
The electronic skin hold back an raiment of magnetoresistive sensor foils which sense both inactive and dynamic charismatic fields . The sensors are made from layers of atomic number 27 and atomic number 29 , with polyethylene terephthalate ( PET ) film . Information about the sensor ’s proximity to a magnetic field is transmitted wirelessly to an outside equipment that has LED indicators , giving a visual theatrical of the length .
The skin is only about two micrometers thick , which is about one - fifth as wide as a single human hair . A square beat of the material only weighs three grams , which makes it light enough to perch on a soap house of cards , as can be see above . It is also fabulously pliable , as it is able to dilute over 270 % in multiple directions over 1,000 time before wearing out . Conversely , the sensors are still able to function decent if the hide is crumpled up . These features make them well - suited for enjoyment on the hide .

" These ultrathin magnetic sensor with over-the-top mechanical robustness are ideally suited to be wearable , yet unobtrusive and imperceptible for preference and handling aids , " senior author Oliver Schmidt explicate .
In the future , this technology could be used with biomedical implant such as stilted muscles or spliff to find anomalous demeanour , and could also be used to improve the fine motor skills of lenient robotics .
“ The desegregation of magnetoelectronics with ultrathin operative elements such as solar cells , light - emitting diodes , electronic transistor , as well as temperature and tactile detector arrays , will enable autonomous and various smart systems with a multitude of perception and propulsion features , ” the authorswrote in the paper .
