Résumé

A new kind of nanodevice that acts like tweezers through remote actuation by an external magneticfield is designed. Such device is meant to mechanically grab micrometric objects. The nanotweezersare built by using a top-down approach and are made of two parallelepipedic microelements, at leastone of them being magnetic, bound by a flexible nanohinge. The presence of an external magneticfield induces a torque on the magnetic elements that competes with the elastic torque provided by thenanohinge. A model is established in order to evaluate the values of the balanced torques as a functionof the tweezers opening angles. The results of the calculations are confronted to the expected valuesand validate the overall working principle of the magnetic nanotweezers.
