In this paper, a rugged, low cost and very efficient fiber optic displacement sensor is proposed and demonstrated for the measurement of amplitude and frequency of heart rate signal. The proposed sensor is based on intensity modulation technique and uses a bundled POF as a probe. Among these sensors, optical fiber sensors (OFSs) stand out due to their remarkable properties, including resistance to electromagnetic interference. Nowadays, wearable devices are gaining broad interest for a continuous monitoring of the heart rate (HR). One of the most promising methods to estimate HR is the seismocardiography (SCG) which allows to record the thoracic vibrations with high non-invasiveness in out-of-laboratory settings.
Fiber optic strain sensors are an innovative solution designed to measure deformation. These sensors utilize the unique properties of light traveling through fiber optic cables to detect and quantify strain caused by environmental or structural changes. Their non-intrusive nature, high sensitivity, and durability have made them popular for a wide range of. The distributed optical fiber sensors (DFOS) are strain, temperature, and vibration monitoring tools characterized by minimal intrusiveness, accuracy, ease of deployment, and the ability to perform measurements with high spatial resolution.
Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor's current-generated magnetic flux, which reflects off a mirror. The light experiences a reciprocal phase shift as the refractive index, and effective path length, is modulated by the presence of a magnetic field, which optically induces circular. The relative to a reference waveform is an optical intensity value corresponding to the.

A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Depending on the application, fiber may be used because of its small size, or because no electrical power is needed at th. Intrinsic sensorsOptical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time. Extrinsic fiber-optic sensors use an, normally a one, to transmit light from either a non-fiber optical sensor, or an electronic sensor connected to an optical transmitter. A major benefit of e. It is well-known the propagation of light in optical fiber is confined in the core of the fiber based on the total internal reflection (TIR) principle and near-zero propagation loss within the cladding, which is very important f.
