The authors thank Sungwon Lim for intellectual contributions to device and mold design as well as Jambu Jambulingam and Rebecca Grossman-Kahn for creating intravaginal silicone probes using this process. This work is supported by the Bill and Melinda Gates Foundation, the Vodafone Americas Foundation, and the FDA (2P50FD003793).

अन्य सॉफ्टवेयर संकुल भी एक ही परिणाम हासिल करने के लिए इस्तेमाल किया जा सकता है, हालांकि यह प्रोटोकॉल, मोल्ड डिजाइन और उत्पादन कदम के लिए इस्तेमाल किया SolidWorks सॉफ्टवेयर में विशिष्ट शब्दावली और सुविधाओं ?...
