A method and apparatus suitable for monitoring biometrical data (e.g., pH level of a grape) of living organisms is disclosed. A method for monitoring biometrical data includes providing a chemical matter having a chemical agent, contacting the chemical matter with a biological matter, detecting a change in the chemical matter to produce a signal, altering the signal into an electrical signal, and obtaining biometrical data from the electrical signal. An apparatus for determining biometrics data of a living organism includes a capillary tube configured to receive fluid from the living organism, a hydrogel solution having a volume responsive to one or more characteristics of the fluid, a capacitor having at least one plate responsive to the volume of the hydrogel solution, and an inductor coupled to the capacitor. The inductor and the capacitor form a circuit having a resonant frequency. Embodiments of the present invention can advantageously provide a wireless and powerless device for determining biometrics data of living organisms.
