| Research Abstract |
Through the research project, two main achievements are obtained.
(1)A method for simultaneously measuring the loading position and the magnitude of the load force is found out. It uses an H-slit type double beam structure as the deflection mechanism. The effectiveness of the method is verified by FEA simulations and an experimental model. As a result of the finding, we can know the actual magnitude of the load whichever part of the tweezers is gripped by an operator.
(2)Overload prevention is important for a micro tweezers with function of force display. Since unexpected external force may damage it. A new type of overload prevention mechanism is proposed for those tweezers with small deflection mechanism.
