Fuente: WIPO "tomato" A biological sensor according to an embodiment of the present technology includes a first antenna conductor, a second antenna conductor, and a power detection unit. The second antenna conductor is a conductor different from the first antenna conductor, and is electrically coupled to an organism connected to an earth ground directly or by capacitive coupling. The power detection unit detects AC power to be generated between the first antenna conductor and the second antenna conductor in accordance with a resistance component of the organism relative to the earth ground.
