During recent years, interests in development of sensors for Internet of things (IoT) have increased. Electronic tattoos (e-tattoos) are a group of newly developed wearables with the thickness range of few to hundreds of micrometer and they can be laminated on skin and be used as display or sensors with applications in e-health, e-skin and human machine interface and IoT. Here we present the thinnest, multimodal, mechanically and optically imperceptible graphene based electronic tattoo (GET) sensors. The overall thickness of GET is less than 500 nm which results in conformal contact to the microscopic features of skin, low electrode skin interface, low susceptibility to motion artifact and high signal to noise ratio. Because of low areal mass density of GET, it attaches to skin without the use of any adhesive or tape just by Van der Waals which make is desirable for application in the area with dedicate skin such as face and around eyes. GET has been successfully used for electroencephalography (EEG), Electrocardiography (ECG), electromyography (EMG) and skin temperature and hydration sensing. Also the application of GET for human machine interface has been demonstrated through using GET for electrooculography (EOG). The electrical signa
