Hi, My Name Is Danielle Frisby And I Actually Have

Hi, My name is Danielle Frisby and I actually have several questions that I am hoping that you may be able to answer.
1. I happen to be familiar with the home radiation therapy and the WBAN sensor nodes. There happens to be a wireless body area network sensor nodes in the form of a crystalized sugar. I am not familiar with the name, which I am hoping that you may tell me. if you are familiar with the name of this crystalized sugar sensor node, then I am sending my question in the right direction. Are there ways to get rid of these such nodes? I have been able to locate any information in regards to this. It would be greatly appreciated if you can be of assistance.
Thank You,
Danielle L. Frisby
