Sensors and sensorsystems for in vivo monitoring

“…It is the combination of the two that makes the entire device successful. In recent work, a generic interface circuit has been developed to cope with the typical deficiencies of capacitive sensors [ 15,16]. In the C-V converter, the sense capacitor Cx is converted to a proportional voltage.…”

“…In many cases, additional circuits have been added to correct for the non-linearities and the lack of selectivity of the devices. For instance, capacitive pressure transducers require specific drivers and measurement circuits in the close vincinity of the sensor to cope with the parasitic effects, as has been discussed above [16,26,27 ]. The recent developments in semiconductor technology, offering single chip microcomputers at moderate sizes, have created interesting opportunities for the adaptation in miniaturised telemetric systems.…”

Flexible Piezoelectric Acoustic Sensors and Machine Learning for Speech Processing

“…The uniform sensitivity over voice frequency range enables the easy processing of speech recognition with single channel. However, the condenser‐type sensor has demerits such as insufficient sensitivity, limited recognition distance, high power consumption and the unstable circuit of large amplification . The piezoresistive sensor detects the sound by sensing the resistance change depending on the movement of membrane .…”
