In this study, in order to improve an easiness of use for the power assist suit used in nursing care, a hands-free activation device for supplying air to the power assist suit which was developed in our previous study was proposed. After detecting that the caregiver stooped down by using the sensor, compressed air is supplied to the artificial muscles by performing another action. As another action, 3 methods were proposed, which are (1)Use of time lag, (2)Use of bone conduction microphone, and (3)Use of proximity sensor. Mental workload of each activation method was evaluated using CSTLX method, and accuracy of the detection of air supply timing in each activation method was investigated. In addition, effectiveness of the power assist suit was verified through evaluation experiments of lifting and taking down the heavy object.
