摘要:
The purpose of this invention is to provide a life indicator which can detect an occurrence of growth and obtain various information based on it. A life indicator of this invention having at least a sensor portion, a sending circuit, a receiving circuit and a light emitting diode. The sensor portion is adapted to be applied with a pressure based on an elongation of a positive plate directly or indirectly, so as to detect the applied pressure as a change of electric parameter.
