The present study describes the MEMS-based piezoelectric switch to activate the event-driven wireless sensor node for chicken health monitoring system. We have fabricated the switch composed of “S” shaped piezoelectric cantilever and proof mass, where the resonance is 24 Hz. When the switch has been vibrated at 4, 6, 8, and 12 Hz, which is close to the chicken movement frequency, the input vibration...
Organic optical photodiodes (OPDs) have attracted considerable interest in fields using photonic devices because they present the potential for use as flexible photodetectors for large areas. To elucidate their applicability to radiation measurements, OPDs with a classical heterojunction structure were fabricated and used for X-ray measurements. The device, whose structure was ITO (150 nm)/ ??-NPD...
We have developed the digital output piezoelectric accelerometer using CMOS-compatible AlN thin films. The AlN thin films were deposited by sputtering. The multilayer of Pt/Ti/AlN/Pt/Ti/SiO2 has been fabricated into the piezoelectric accelerometers, where the patterned AlN thin films are arrayed in parallel and electrically connected in series. The sensitivity of the fabricated accelerometer reaches...
We propose a digital output piezoelectric accelerometer for chicken health monitoring. The accelerometer has patterned Pb(Zr, Ti)O3 (PZT) thin films electrically acc connected in series, which accompany CMOS switches. The elerometer converts acceleration into number of on-state CMOS switches, which can be called as "digital output". Since the accelerometer are based on piezoelectric effect,...
