The use of video capsules for noninvasive explorations of the digestive tube is progressively increasing today. At present, the motion of these wireless endoscopic devices cannot be controlled and they proceed by means of visceral peristalsis and gravity. Aimed at enabling a motion control, the technique described here uses an external magnetic field(More)
Wireless capsule endoscopy (WCE) allows for comfortable video explorations of the gastrointestinal (GI) tract, with special indication for the small bowel. In the other segments of the GI tract also accessible to probe gastroscopy and colonscopy, WCE still exhibits poorer diagnostic efficacy. Its main drawback is the impossibility of controlling the capsule(More)
The use of robotic instruments capable of assisting medical staff during interventional or diagnostic procedures is growing rapidly today. Recently, a robotic system (Niobe, Stereotaxis Inc., USA) has been developed for navigating magnetically enabled tools inside the human body by controlling a magnetic field. This paper reports the fundamentals of this(More)
Artificial sensory motor systems are now under development in a truly wearable form using an innovative technology based on electroactive polymers. The integration of electroactive polymeric materials into wearable garments endorses them with strain sensing and mechanical actuation properties. The methodology underlying the design of haptic garments has(More)
This paper describes a technique to control the navigation of traditional wireless endoscopic capsules and reports preliminary proof-of-concept investigations. These capsules are used for noninvasive explorations of the digestive tube. At present, their motion cannot be controlled and they proceed by means of the visceral peristalsis. In order to enable(More)
This paper describes the early conception and latest developments of electroactive polymer (EAP)-based sensors, actuators, electronic components, and power sources, implemented as wearable devices for smart electronic textiles (e-textiles). Such textiles, functioning as multifunctional wearable human interfaces, are today considered relevant promoters of(More)
AIM To report original and review existing data on safety and performance of large-needle aspiration biopsy (LNAB) histology in the preoperative selection of palpable thyroid nodule. METHODS AND RESULTS The English literature and original data were reviewed or analysed. The literature on LNAB of thyroid nodules did not report any complications. A study on(More)
To detect electrocochleographic (ECochG) potentials generated by the cochlea in response to auditory stimuli, either transtympanic or tympanic/extratympanic electrodes are currently used. The first are invasive, while the second are arranged in contact or very close to the tympanic membrane (TM). To avoid the discomfort and the risks inherent to the(More)
Ingestible video capsules enable today non-invasive and comfortable gastrointestinal explorations. As such, capsule endoscopy is progressively emerging as an attractively simple wireless technology for optical investigations of the digestive tube and, in particular, as a useful complementary diagnostic tool with respect to traditional probe endoscopy.
