A sensing and monitoring transducer for detecting blood sugar levels of a person, the transducer being in the form of a miniature enclosure implanted in the person's bloodstream. The enclosure has a chamber, filled with a standard osmostic solution, closed on one side by an osmostic semi-permeable membrane and at another end by a flexible impermeable diaphragm carrying an electrical contact. Transfer of fluid from the chamber containing the standard osmostic solutions through the semi-permeable membrane as a function of variations in blood sugar level causes the flexible diaphragm to be deflected in one direction or the other for placing the electric contact carried by the diaphragm in engagement with one or the other of a pair of fixed electrical contacts, such as to remotely operate appropriate peripheral equipment such as low and high blood sugar level alarms, or insulin and glucose pumps injecting respectively a dosage of insulin and of a glucose solution in the person's bloodstream to maintain the blood sugar level within acceptable limits.
