INTRODUCTION One of a surgeon's most important tools is a highly developed sense of touch. Surgeons rely on sensations from the finger tips to guide manipulation and to perceive a wide variety of anatomical structures and pathologies. Unfortunately, new surgical techniques separate the surgeon's hands from the surgical site. These techniques include(More)
This paper presents a tactile sensor that provides transient event information at the jinger-object interface. The multi-element stress rate sensor consists of piezoelectric polymer strips molded into the surface of the rubber " skin " covering the robot finger tip. These piezoelectric elements provide localized information important to manipulation(More)
Early detection and removal of small pulmonary nodules significantly improves long term survival rates for patients with lung cancer. To aid in the localization of these tumors during video assisted thoracoscopic surgery (VATS), a tactile imaging system (TIS) is presented. The system consists of a capacitive array sensor mounted on a minimally invasive(More)
We synthesized various hollow oxide nanoparticles from as-prepared MnO and iron oxide nanocrystals. Heating metal oxide nanocrystals dispersed in technical grade trioctylphosphine oxide (TOPO) at 300 degrees C for hours yielded hollow nanoparticles retaining the size and shape uniformity of the original nanocrystals. The method was highly reproducible and(More)
Although renovascular hypertension is a rare disease, it is associated with 5–10 % of cases of childhood hypertension. It is a potentially treatable cause of hypertension, and is often caused by renal artery stenosis (RAS). The most common cause of RAS in children is fibromuscular dysplasia (FMD). The options for treating RAS depend on the location,(More)
Menkes disease is an infantile-onset X-linked recessive neurodegenerative disorder caused by diverse mutations in a copper-transport gene, ATP7A. Affected patients are characterized by progressive hypotonia, seizures, failure to thrive and death in early childhood. Here, we report a case of Menkes disease presented by intractable seizures and infantile(More)
This paper presents initial results in integrating touch with vision for delicate manipulation tasks. A generalizable framework of behavioral primitives for tactile and visual feedback control is proposed. Since vision provides position and shape information at a distance, while tactile provides small-scale geometric and force information, we focus on the(More)
