Wireless thermometer on a film-like substrate using quartz vibrator
First Claim
1. A wireless thermometer comprising:
- a heat insulator having a predetermined thickness, a predetermined thermal resistivity, and a first principal surface and a second principal surface opposite each other;
one or more first temperature detecting means disposed on the first principal surface of the heat insulator;
one or more second temperature detecting means disposed on the second principal surface of the heat insulator;
a first antenna connected to the first temperature detecting means and configured to transmit a first detection signal generated by the first temperature detecting means; and
a second antenna connected to the second temperature detecting means and configured to transmit a second detection signal generated by the second temperature detecting means,wherein the first antenna and the second antenna are spaced apart by a predetermined distance in a direction parallel to a thickness direction of the heat insulator, and disposed so that antenna forming regions are at least partially overlapped with each other as viewed in the direction parallel to the thickness direction.

Abstract
A wireless thermometer is provided, which measures a deep temperature with high accuracy and has an improved communication distance. A wireless thermometer includes a flat film-like substrate. A quartz crystal vibrator and an antenna are disposed on a principal surface of the substrate. A quartz crystal vibrator and an antenna are disposed on the other principal surface of the substrate. A winding conductor of the antenna is substantially symmetrical with a winding conductor of the antenna with respect to the substrate. A lead conductor of the antenna is connected to the winding conductor at one end and is connected to the quartz crystal vibrator at the other end. A central portion of the lead conductor is bent. By folding the central portion, the quartz crystal vibrator can be positioned opposite the quartz crystal vibrator with a heat insulator interposed there between.
