Background
The fast-paced and high-intensity living and working states of modern society lead more and more people to be troubled by the problems of cervical vertebra discomfort, waist pain and the like. Along with the increase of the income of residents, the massage relaxation demands of people are in a remarkable rising trend, and higher requirements are provided for product portability and control experience while comfortable massage experience is pursued. The widespread use of TENS electrical stimulation technology has prompted the emergence of a range of small massagers, which, while having a compact size and providing a comfortable massage experience, still use the body buttons for manipulation, which is extremely inconvenient when placed on the back of the neck, etc. In addition, since electrical stimulation requires adjustment of multiple parameters, the massager needs to be set up in a cumbersome manner each time it is restarted. The electric stimulation massager is easy to cause error touch when the massage head is in poor contact with the skin or is not closed in time, thereby bringing discomfort experience with strong electric shock feeling to users. In conclusion, the portable massager based on the TENS technology still has great space for improving the manipulation experience.
