Abstract:
Methods, apparatuses, and methods for manufacturing apparatuses that differentially detect beta and/or gamma rays are described. One radiation sensor described herein has operational amplifier(s), two blocking layers capable of blocking beta rays, and two photodiodes. The first photodiode is disposed between the blocking layers and thus isolated from incident beta rays. Accordingly, the first photodiode is capable of detecting gamma rays and providing a current corresponding to detected gamma rays to an operational amplifier. The second photodiode is disposed on one of the blocking layers and is capable of detecting beta rays and gamma rays and providing current corresponding to detected beta and/or gamma rays to an operational amplifier. The operational amplifiers convert the currents into voltage pulses which are used to, for example, determine if beta and/or gamma rays are detected and the amount/level of detected rays.
Abstract:
A method for measuring skin by an electronic device according to various embodiments of the disclosure comprises: an operation of irradiating at least one light into skin to which a patch is adhered; an operation of detecting at least one reflected light on the basis of an amount of moisture in the skin, which is changed by physiologically active substances injected through the patch, corresponding to the irradiated light; an operation of generating patch adherence information indicating a skin adhesive state of the patch on the basis of the detection result of the at least one reflected light; and an operation of providing the generated patch adherence information to an output unit or a communication unit.
Abstract:
Provided is a wrist wearable terminal including: a body portion including a function module; a coupling portion fastening the body portion on a wrist; and at least one strap portion linking the body portion and the coupling portion and including at least one function module that is coupled to the function module of the body portion via a signal line to convert or activate a use of at least one function of the wrist wearable terminal depending on a state of wearing of the wrist wearable terminal.
Abstract:
According to various embodiments of the disclosure, a microneedle patch may include: microneedles including a viscous composition; an adhesive sheet adhered to the skin; and a base sheet having the microneedles arranged thereon, wherein the shape of the microneedles has a spirally-twisted screw shape so as to have a first incline facing a first direction and a second incline facing a second direction, which is the direction opposite to the first direction, and the diameter of a base part facing the base sheet gradually decreases toward an end portion.
Abstract:
A method of measuring a pulse wave velocity difference in a mobile device includes: obtaining electrocardiogram (ECG) information of an object through a first electrode that contacts a first surface of the object and is included in the mobile device and a second electrode that contacts a second surface of the object and is included in the mobile device; obtaining blood flow change information of the first surface and the second surface by using a first optical sensor that contacts the first surface and is included in the mobile device and a second optical sensor that contacts the second surface and is included in the mobile device; obtaining pulse wave velocity information to the first surface and pulse wave velocity information to the second surface based on the obtained ECG information and the obtained blood flow change information of the first surface and the second surface; and measuring pulse wave velocity difference information based on the pulse wave velocity information to the first surface and the second surface.
