N2  - Point-of-care applications and patients' real-time monitoring outside a clinical setting would require disposable and durable sensors to provide better therapies and quality of life for patients. This paper describes the fabrication and performances of a temperature and a pH sensor on a biocompatible and wearable board for healthcare applications. The temperature sensor was based on a reduced graphene oxide (rGO)layer that changed its electrical resistivity with the temperature. When tested in a human serum sample between 25 and 43 °C, the sensor had a sensitivity of 110±10 ?/°C and an error of 0.4±0.1 °C compared with the reference value set in a thermostatic bath. The pH sensor, based on a graphene oxide (GO)sensitive layer, had a sensitivity of 40±4 mV/pH in the pH range between 4 and 10. Five sensor prototypes were tested in a human serum sample over one week and the maximum deviation of the average response from reference values obtained by a glass electrode was 0.2 pH units. For biological applications, the temperature and pH sensors were successfully tested for in vitro cytotoxicity with human fibroblast cells (MRC-5)over 24 h
