10.3　Types of E-Skin Devices and Their Application...

The function of skin is very complicated.Therefore，the corresponding e-skin devices should be multifunctional（see extended reading 2）.First of all，the e-skin devices need to simulate the tactile sensing of the skin，so that patients with damaged skin or missing limbs can reconstruct the skin's tactile sensing to the external environment.It can also give the robot more precise tactile responsiveness，to complete more complicated human-computer interaction tasks.Secondly，as a wearable device，the e-skin devices can also be endowed with chemical sensing properties，including sensing the chemical components of body fluids and gases，so as to realize the function of human health monitoring.In addition，the e-skin devices can also be integrated with disease treatment functions.When a change in human health is monitored，the e-skin devices can responsively release its loaded specific drug to treat the disease.In addition，for wearable devices，its energy supply is also very important.Through the material and device structure design，the e-skin devices can be used for energy storage and energy supply.In addition，by integrating multiple functions，multifunctional eskin devices can be prepared，thereby realizing the intelligence of the e-skin，which can be used to monitor blood pressure，respiratory rate，body movement，body temperature changes，etc.In this section，the e-skin devices with different functions will be briefly introduced.(https://www.daowen.com)
