NON-INTERFERENCE BLOOD GLUCOSE SCREENING BASED ON LASER BEAM AND GALVANIC SKIN RESPONSE RECORDER

Diabetes is a metabolic disorder due to high blood sugar level and Insulin is a hormone that regulates blood sugar. Diabetes over time leads to serious health issues. The main goal for controlling diabetes is to control the blood sugar. For this, a Continuous monitoring of blood glucose level plays a vital role. BGS is important to bypass the problems raising due to irregular blood glucose levels in diabetic patients. Current blood glucose screening (BGS) ways are harmful as they desire a finger prick blood sample, a repeatedly hurtful process that builds the danger of infection. Laser beam-based sensors have determined a remarkable potential for BGS. The NearInfrared (NIR) based BGS approaches in current use have deficiencies such as the intake of light in human tissue, greater signal to noise ratio (SNR) and low efficiency, these drawbacks have prevented NIR approaches from being engaged for commercial BGS operations [2]. In this paper, a simple and cost-efficient laser beam and galvanic skin response (GSR) recorder is implemented. This monitoring device has three major technical advantages over NIR. Unlike NIR red laser beam has better transmittance through human tissue [3]. In addition, when correlated to NIR refractive index of laser beam is more sensitive to deviations in glucose level concentration resulting in faster response. Inclusion of GSR in this system helps it be more efficient and precise NIR [4]. This combined system has more efficiency than other non-interference blood glucose screening systems out which can be easily used on daily basis to monitor blood glucose level [5].
