Abstract: There is provided a capacitive pressure sensor comprising: a dielectric layer; a first electrode disposed on a first surface of the dielectric layer and to which a pressure is applied; a second electrode disposed on a second surface of the dielectric layer opposite to the first surface and including a plurality of unit electrodes having a predetermined shape; and a measuring device configured to detect a measurement value of a capacitance of the dielectric layer for each unit electrode by causing a potential difference between the first electrode and the second electrode. An electrode area of the unit electrode is determined using an actual measurement data indicating a relationship between a change amount of the measurement value detected for each unit electrode by the measuring device when a pressure is applied to the first electrode and the electrode area of the unit electrode and using a minimum value of the change amount of the measurement value determined by conditions including the number of detection steps of a pressure detected for each unit electrode by the measuring device.

Abstract: A wireless detonation system (1) includes a blasting operation device (40), a detonator (10), and a relay device (30). The blasting operation device (40) is disposed at a distance from a blasting face (71) and wirelessly transmits a first downstream signal at a first frequency. The detonator (10) is loaded in a blast hole (72) in the blasting face (71), and has a receiving coil (12) for wirelessly receiving a second downstream signal at a second frequency lower than the first frequency. A relay device (30) includes a first transmitting-receiving antenna (35) that wirelessly receives the first downstream signal, a relay processor (32) that wirelessly receives the first downstream signal and processes it into the second downstream signal to be wirelessly transmitted at the second frequency, and a second transmitting-receiving antenna (37) that transmits the second downstream signal. The second transmitter-receiver antenna (37) is loaded into an insertion hole (74) in the blasting face (71) aligned with the blast hole (72).
