Physiological parameters
Wearables for healthcare - Physiological parameters, technologies, challenges

In order to develop wearable solutions, it is necessary to characterize a number of physiological parameters using the methods described in this section. The order of magnitude of these parameters is given in table 1. Based on electronic, mechanical (piezoelectric, piezoresistive, capacitive transducers), optical or electrochemical principles, numerous sensors have been developed and can be integrated into wearables for the non-invasive measurement of vital signs.
