This is a very large population of patients with diabetes in daily life, and it's difficult to monitor the glucose level for these patients, it needs to get blood sample on the spot nearly each time. Althoughthere is now noninvasive glucometer available, its expensive price is what most people can't affordable.
But researchers from Washington State University created a 3D printed glucose biosensor. It can accurately measure glucose level in sweat through a biosensor, since sweat is expelled from the skin, which is more suitable for common patients to do daily monitoring.
They produced nanometer materials with electroconductibility and flexibility by 3D printer, which helps to save more materials, and makes the biosensor more sensitive than traditional electrode.
