Abstract: Disclosed are a microneedle patch, a realtime blood sugar monitoring device, and a realtime blood sugar monitoring method using the realtime blood sugar monitoring device. The realtime blood sugar monitoring device causes a different color to be reversibly expressed according to the concentration of sugar included in the skin of a human body, and, thus, if the device is utilized, the concentration of the sugar in the human body can be measured in realtime in a minimally invasive manner. Also, the present invention shows the measured concentration of the sugar by connecting to a wearable device and, thereby, allows a user to more conveniently check changes in the concentration of the sugar in realtime.

Abstract: Disclosed herein is a four-pole plug for connection to a PCB. The four-pole plug includes a plug body unit (10) which has a long cylindrical shape and is connected to a jack of an acoustic apparatus, a connection terminal unit (20) which is coupled to an end of the plug body unit, and a terminal housing (30) which receives the connection terminal unit therein and has an opening at a predetermined position so that a portion of the connection terminal unit protrudes from the terminal housing through the opening.

Abstract: The present invention relates to a method of automatically setting a unit of measurement of a bio-data measuring device. The bio-data measuring device automatically sets a country belonging to a corresponding location as location information is determined, and automatically selects a unit of measurement of the set country depending on automatic setting for countries. When bio-data is measured by measurement means, operation means calculates a bio-data measurement value depending on a reference unit and a calculation formula, and determines whether the automatically selected unit of measurement of the set country is identical to the reference unit. If the automatically selected unit of measurement is not identical to the reference unit, the operation means converts the calculated bio-data measurement value into a numerical value based on the automatically selected unit of measurement of the set country. The converted numerical value and the automatically selected unit of measurement are displayed.

Abstract: Disclosed herein is a method of correcting erroneous measurement results in a biosensor. The method includes the steps of: (a) applying a first voltage from a voltage generator 12 to a test strip 10 when a blood sample is applied on the test strip 10, and measuring an electric current generated from the test strip within one second of applying the first voltage by a microcontroller unit (MCU), and then calculating a hematocrit value of the blood sample using the measured electric current value! (b) applying a second voltage from the voltage generator to the test strip after calculating the hematocrit value of the blood sample, and measuring an electric current generated from the test strip within a predetermined time of applying the second voltage, and then calculating a glucose level using the measured electric current value; and (c) correcting the glucose level in (b) by using the calculated hematocrit value in (a).
