    Controllable Tension Adjustment Design in Kinesio Taping
    (2019) Evren, Elif; Zaim, Zeynep Ezgi; Oter, Seckin; Kocak, Onur
    In this study, two different devices were designed to enable the kinesio banding to reach the desired tension level for correct treatment and the data obtained from these two different systems were compared and recorded. The first designed measuring device is based on software processing of optical permeability. Depending on the increase and decrease in the force applied to the belt, the pores on the belt expand or contract. Intense light is sent over the band. The light reaching the receiver below the band varies depending on the pore width of the band. The information received simultaneously is divided into levels by the software and notified to the user. Another planned performance design is tension detection via pressure sensor. In this method, the pressure sensor between the kinesio tape and the platform changes value due to the pressure force applied to it as the belt tensiones. In both designs, the desired tension levels for the tape were obtained and verification was performed by expert physiotherapists.

    A Low Cost Design Non-invasive Glucose Monitoring Experimental Setup
    (2018) Evren, Elif; Kocak, Onur
    In this non-interventional study, infrared glucose measurement, a non-invasive method of blood glucose measurement that is painless, hygienic and more practical, was investigated and a data supporting the feasibility of this method was obtained using a low-cost assay. Another goal of this study is to demonstrate that the infrared transceiver array can measure optical changes due to different solvents and different glucose concentrations. The data are obtained and compared based on the concentration of glucose in each solution and solution. The closed system we use for this study is completely isolated from the outside environment and the 950nm infrared receiver transmitter installed with arduino is prevented from being influenced by different light sources. In our study, water, isopropyl alcohol and glycerol were used as solvent for glucose determination. Our receiver-transmitter is the most commonly used infrared transceiver in the 950-nm wavelength range. The data received from the receiver was converted to volt value with Arduino software and significant values were created. As a result of the measurements, it was observed that the voltage value changed due to the concentration of the solution. As the glucose concentration in the solution increased, the voltage value decreased.
