Design and Control of a Piezoelectric-Driven Microgripper Perceiving Displacement and Gripping Force [PDF]

Micromachines, 2020
A piezoelectric-driven microgripper with three-stage amplification was designed, which is able to perceive the tip displacement and gripping force. The key structure parameters of the microgripper were determined by finite element optimization and its ...

Decoding gripping force based on local field potentials recorded from subthalamic nucleus in humans [PDF]

eLife, 2016
The basal ganglia are known to be involved in the planning, execution and control of gripping force and movement vigour. Here we aim to define the nature of the basal ganglia control signal for force and to decode gripping force based on local field ...

Method for the Detection of Tumor Blood Vessels in Neurosurgery Using a Gripping Force Feedback System. [PDF]

Sensors (Basel), 2019
Avoiding unnecessary bleeding during neuroendoscopic surgeries is crucial because achieving hemostasis in a narrow operating space is challenging. However, when the location of a blood vessel in a tumor cannot be visually confirmed, unintentional damage ...
