Abstract: The present invention relates to a patch type thermometer containing a polymer that can be phase changed from a solid phase to a liquid phase. The patch type thermometer provided in an aspect of the present invention demonstrates high precision since it does not include conductive particles which have been a reason of disadvantage of the conventional temperature sensor, and has the effect of no temperature deviation in repeated temperature measurements because it is composed of such a single polymer material that is phase changed in a specific temperature range so that the polymer material can be reversibly changed in the volume and shape.

Abstract: The present invention relates to a device for measuring grip strength including a basis; a cover coupled to the basis to form an enclosed pressure space separated from the outside; a cap disposed between the basis and the cover and configured to form a sensing space separated from the pressure space; magnets mounted on the cap or the basis to form a magnetic field; and a magnetic sensor for detecting change in the magnetic field. With this configuration, when measuring the grip strength of the user's hand, accuracy or sensitivity may be increased.
