Even larger pulp defects were rearranged in a round shape and good soft tissue coverage of the distal phalanx was achieved. Results: The results of both, conventional film dressing and silicone finger cap treatment, were excellent with no hypersensitivity and no restrictions in sensibility and motility. This included photographs and microbiological results from wound fluid analyses, whenever available. We summarized clinical data for each patient. 12 patients were treated with a novel silicone finger cap. Methods: We report on 34 patients in between 1 and 13 years with traumatic fingertip amputations primarily treated with occlusive dressings. We therefore treated selected patients with a novel silicone finger cap with an integrated wound fluid reservoir that enables atraumatic routine wound fluid aspiration. Due to the lack of mechanical protection, the leakage of maloderous woundfluid and the sometimes challenging application, conventional film dressings have their problems, especially in treating young children. The underlying mechanisms for this form of regenerative healing as well as for the resilience to infections are not known. Despite bacterial colonizations, proceeding infections are not reported with this management.

Introduction: Human fingertips are able to regenerate soft tissue and skin after amputation injuries with excellent cosmetic and functional results when treated with semiocclusive dressings. heilten 42 Fingerkuppendefekte innerhalb 2 bis 6 Wochen schmerzfrei und voll belastbar mit kaum sichtbaren Narben, harmonischen Papillarlinien, Rückkehr der Schweißsekretion und einer statischen Zwei-Punkte-Diskrimination von 2–8 mm. Nach Mennen und Wiese heilten 200 Fingerkuppendefekte (zum Teil mit Nagelbeteiligung und freiliegender Endphalanx) innerhalb 20–30 Tagen mit schönem Remodelling der Fingerbeere, guter Qualität des Epithels einschließlich der Hautleisten sowie nahezu normaler Sensibilität.

On account of the excellent responses mentioned, the sensor could detect human motion and has also been demonstrated in this paper. Furthermore, the sensing strip embedded on a soft robotic pneumatic actuator mounted on a test rig showed excellent movement detection response upon actuation. We present a super-elastic, ultrasoft natural rubber composite containing multiwalled carbon nanotubes in presence of a hydrofinished oil-based softener. The resulting conducting elastomer offered a line-up of compelling characteristics such as low electrical percolation (1000). A piezoresistive strain sensor embedded-soft robotic arm has been a challenging task in terms of surface compatibility, shape and dynamics of the soft robotic components. Piezoresistive soft composites are ubiquitous in strain sensing that manifests in a dramatic increment of electrical resistivity upon elongation.
