Real-time contact force measurement: a key parameter for controlling lesion creation with radiofrequency energy.
R adiofrequency (RF) energy, the dominant energy source for the treatment of various arrhythmias by catheter abla-tion, has replaced most other treatments for the effective suppression of supraventricular and ventricular arrhythmias. 1 With expanding indications, it has become increasingly clear that the success and sustainable effect of RF ablation depends on a critical understanding of the bi...
متن کاملMeasurement of contact stresses using real-time shearing interferometry
Liming Xu Hareesh V. Tippur Carl-Ernst Rousseau Auburn University Department of Mechanical Engineering Auburn, Alabama 36849 Abstract. The optical method coherent gradient sensing, a real-time lateral shearing interferometry, is proposed for measuring contact stress fields under static and dynamic loading conditions. Feasibility of the method is first established under quasi-static conditions. ...
متن کاملReal-time measurement of the three-axis contact force distribution using a flexible capacitive polymer tactile sensor
In this paper, we report real-time measurement results of various contact forces exerted on a new flexible capacitive three-axis tactile sensor array based on polydimethylsiloxane (PDMS). A unit sensor consists of two thick PDMS layers with embedded copper electrodes, a spacer layer, an insulation layer and a bump layer. There are four capacitors in a unit sensor to decompose a contact force in...
متن کاملMeasurement of Poisson’s ratio with contact- resonance atomic force microscopy
We describe contact-resonance atomic force microscopy ͑AFM͒ methods to quantitatively measure Poisson's ratio or shear modulus G at the same time as Young's modulus E. In contact-resonance AFM, the frequencies of the cantilever's resonant vibrations are measured while the tip is in contact with the sample. Simultaneous measurement of flexural and torsional vibrational modes enables E and to b...
متن کاملMeasurement of palatolingual contact pressure and tongue force using a force-sensor-mounted palatal plate
In this paper, we report on a 15-cantilever-type, force-sensormounted palatal plate capable of high sensitivity and accurate measurements of the palatolingual contact pressure and pattern that occur during consonant phonation. This paper also describes measurements of tongue force based on the results of the palatolingual contact pressure measurements that the 15-cantilever-type, force-sensor-m...
