FSR based force torque transducer design

open access: yes, 1993
This thesis report discusses the design, construction and calibration of two force-torque transducers for use in a force control override of a rate control system. Pre-loaded force sensing resistors were used in a computer model to determine the 6-umber and location of sensors necessary to resolve three forces and three moments.

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...
