Are you following the Tec-Med non-invasive glucose meter? I guess it uses polarity to measure blood glucose in real time.

TecMed Inc. in Albuquerque, New Mexico, says that it is developing the TecMed Gluco/Check, a totally noninvasive glucose monitor. It is an electro-optical device (i.e., it combines electronics and optics to perform a certain function). That function is to measure concentrations of glucose in the human body.

TecMed’s technological approach is known as “polarimetry,” the science of measuring the rotation of the plane of polarized light. Its product is planned to be no larger than an ordinary cellular telephone, to provide the user a direct readout of his or her glucose levels, and to be easy and durable enough for a young child to use. It is planned to be priced in the $2000 to $2500 range, but will require no supplies or peripherals. The company doesn’t say when it will be available.
