A soft touch

Measuring the force it takes for a hand to grasp an object requires sensors to be placed on the fingertips, but these sensors will interfere with or affect how much force ends up being applied. Lee et al. developed a nanomesh sensor built from a series of electrospun materials (see the Perspective by Liu). Using a robotic tester, they show that this device can repeatably detect the pressure involved in gripping an object. They also show that the sensors can be attached to human fingers and that this does not affect the force used to grasp an object.
