Guiding surgery and “touching” with sensors
The SurgiMag partners are developing computer-aided surgical techniques by combining imaging technology and magnetic localization. Tactile sensors for texture recognition have many possible applications.
Computer-aided surgery
SurgiMag is a Minalogic project whose main goal is to combine imaging and magnetic localization for computer-aided surgery. Our main partners are Grenoble-area companies: SurgiQual Institute, Cedrat Technologies and Movea
The project focused on realization and characterization of small sensors able to reach high precision with high signal-to-noise ratio, solutions to detect and compensate for magnetic perturbations from nearby objects such as tables or surgical tools, realization of a clinical application for interventional radiology based on magnetic localization .
Artificial touch thanks to 3D effort sensor
Leti’s focus on smart devices in 2009 included the conception, characterization and use of an artificial touch system for tactile texture recognition. The artificial finger includes a triaxial force sensor developed by Leti, which is covered with a polyurethane skin. The finger is rubbed against surfaces with a robotic arm we conceived.
Tactile sensors for texture recognition have potential applications in a wide range of fields. We focused on paper and fabric, with an eye on developing the capability to characterize textures as consumers would, and other potential applications include skin softness characterization for the cosmetic industry, dexterous object manipulation for robotics, and tactile sensing for minimal access surgery.
