To achieve this, on-body sensors are the most commonly used technology at present, and they can be found in fields as healthcare applications, physical training, emergency rescue service, and law-enforcement. People have an increasing interest obtaining information about their health, the world around them and the interactions with others during their daily life. Smart textiles and wearable devices are being developed everyday by researchers with the objective of substitute standard electronic components. The adaptation of the weaving process to accomplish a fully integrated sensor provides a better repeatability than previous embroidered sensors and opens a door to being commercially produced. The presence detection is also demonstrated, which makes the capacitance variation change from a 10% of capacitance variation when the chair is empty, to a capacitance variation of 170% when a person is sitting on it. The woven sensor results demonstrate its functionality over moisture measurement where sensor capacitance changes from a minimum of 9.74 pF at 30% RH to a maximum of 2.31 uF at 90% RH. Subsequently, presence response is evaluated measuring the capacitance of the woven sensor meanwhile a person is sitting down and getting up. In order to evaluate the sensor response to moisture, capacitance has been measured by means of an LCR meter from 20 Hz to 20 kHz in a climatic chamber with a swept of the relative humidity (RH) from 30% to 90% at 20 ☌. The sensor consists in an interdigitated capacitance prepared to measure moisture and/or presence detection. In this paper, a full textile capacitive woven sensor integrated over a textile substrate is presented.
