“…where S A and S B are sensitivity of the sensor towards target gas A and interference gas B. Additional reports involving HAp doped with graphene, 195 Au 196 and cellulose nanofibers 197,198 revealed varying levels of sensitivity towards NH 3 with the measured values tabulated in Table 6. Interestingly, the predominant crystal orientation of HAp in most reports was along the c-plane with the exception of the report in ref.…”

“…The final electrode structure with a thickness profile of 50/200 nm (Ti/Cu) was prepared on the PZT surface. A schematic diagram of the prepared highaspect-ratio cantilever-type piezoelectric transducer is shown in figure 3(g); this sensor consists of a microwire, a PZT thin film, and an electrode layer [36]. Table 1 presents the material parameters of the piezoelectric and electrode.…”

Inspired by the highly sensitive hairs of creatures in nature, this work proposes a high-aspect-ratio piezoelectric sensor that is processed using electrohydrodynamic jet printing technology. A thin layer of piezoelectric material is directly written on the surface of tungsten steel microwire by electrohydrodynamic jet printing. The piezoelectric thin-film was crystallized by high-temperature annealing and be bonded fully to the microwire. The annealed piezoelectric thin-film was then sputtered with copper electrodes which forms a piezoelectric hair-like sensor with a diameter of 120 μm and an aspect ratio of 300. It was observed that the piezoelectric hair-like sensor generates 18 mV with a displacement bend of 100 μm. The output signal increases linearly with the increase of lateral displacement and velocity. It was examined that the piezoelectric hair-like sensor can detect airflow velocity as low as 0.01 m/s, which shows a lower detection threshold compared to piezoelectric hair-like airflow sensors processed in other ways. In addition, the detection of an airflow velocity of 10 m/s and a response time is 70 ms is obtained using the piezoelectric hair-like sensor, which exhibits large detection range and fast response. The experimental results show that the piezoelectric hair-like sensor has high sensitivity, large detection range and rapid detection response, which is expected to be a high-performance sensor for biosensing and airflow monitoring.
