20150190123 | Steerable Shape Sensing Biopsy Needle - A biopsy needle has a central axis and includes one or more sensing regions, each sensing region formed by a plurality of sensing optical fibers located over a particular extent of said central axis and inside the outer shell of the needle. The sensing optical fibers are coupled to a wavelength interrogator. A steerable catheter has a central axis and outer shell, the outer shell coupled to a plurality of optical fibers in sensing regions and actuation regions, the sensing regions formed over particular extents of the central axis by bonding gratings to the inner surface of the outer shell, and the actuation regions formed by coupling optical energy into shape memory alloys bonded to the outer shell. | 07-09-2015 |

20150292968 | MULTI-AXIS FORCE SENSING SOFT ARTIFICIAL SKIN - A sensor including a layer having viscoelastic properties, the layer comprising a void, the void filled with a fluid; and optionally, a more rigid sensing element embedded within the layer. When a force is applied to a surface of the sensor, the shape of the void changes, causing the electrical resistance of the fluid in the void to change. When included, the more rigid sensing element can bear upon the void to cause the electrical resistance of the fluid in the void to change. A direction and intensity of the force can be determined by measuring the change of the electrical resistance of different voids positioned about the sensing element. The layer can be an elastomer, preferably silicone rubber. The fluid can be a conductive liquid, preferably Eutectic Gallium Indium. The sensing element can be plastic and can have a “Joystick” shape. The voids can take the form of channels or microchannels having a predefined pattern and/or shape. | 10-15-2015 |
