A simple intensity modulated displacement sensor is proposed and demonstrated for sensing the concentration of glucose vin distilled water. For a concentration change of glucose from 0 to 25 % in distilled water, the peak light intensity and its position increases linearly with the concentration due to the increased of the refractive index of the liquid. The measured sensitivities are obtained at around 0.0103 mV/(%) and 0.0229 mm/(%) for the peak voltage and position changes respectively. The stability, high sensitivity and simplicity of the sensor make it suitable for chemical, pharmaceutical, biomedical and process control sensing applications.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
