Patent ID: 8115643

Claim:
An excrement detection sensor comprising: two pairs of conductors extending coaxially in parallel with each other; a carrier body on which the conductors are formed; and a coating body covering the conductors with the conductors being disposed between the carrier body and the coating body, wherein either one of the carrier body and the coating body is formed with urine introduction ports correlating at least one pair of conductors and faeces introduction ports displaced from the urine introduction ports and correlating another one pair of conductors, in which a plurality of urine introduction ports are disposed in a longitudinal direction of the paired conductors and in which when urine enters into the urine introduction ports, the one pair of the conductors are short-circuited and when faeces enters into the faeces introduction ports, the another one pair of conductors are short-circuited; wherein either the one or the another pair of conductors are connected in parallel through a high resistance conductors having a resistance larger than that of the paired conductors.
