A MEMS electrostatic kinetic energy harvester(e-KEH)of about 1 cm2,working at ultralow frequency(1–20 Hz),without any supported additional mass on its mobile electrode,and working even without a vacuum environment is *** prototype is especially suitable for environments with abundant low frequency motions such as wearable *** proposed e-KEH consists of a capacitor with a finger-teeth interdigited comb *** greatly reduces the air damping effect,and thus the capacitance variation remains important regardless of the presence of *** the new design,the energy transduced per cycle of excitation is no less than 33 times higher than the classic design within 10–40 Hz/2 g_(peak),while is 85 times higher at 15 Hz/2 g_(peak).An enclosed miniature ball combined with non-linear stoppers enables the oscillation of the movable electrode through impact-based frequency up-conversion mechanism,which is also improved by the low air *** to this new design,a higher efficiency than the classic gap-closing comb structure is obtained,as a larger range of working frequency(1–180 Hz)in air.A maximum energy conversion of 450 nJ/cycle is obtained with a bias voltage of 45 V and an acceleration of 11 Hz,3 g_(peak).Working with a diode AC-DC rectifier,the proposed KEH is able to support up to 3 RFID communications within 16 s while operated at 11 Hz,3 g_(peak).

Pyroelectric(PE)detection technologies have attracted extensive attention due to the cooling-free,bias-free,and broadband ***,the PE signals are generated by the continuous energy conversion processes from light,heat,to electricity,normally leading to very slow response ***,we design and fabricate a PE detector which shows extremely fast response in near-infrared(NIR)band by combining with the inhomogeneous plasmonic *** plasmonic effect dramatically accelerates the light-heat conversion process,unprecedentedly improving the NIR response speed by 2−4 orders of magnitude to 22μs,faster than any reported infrared(IR)PE *** also innovatively introduce the concept of time resolution into the field of PE detection,which represents the detector’s ability to distinguish multiple fast-moving ***,the spatially inhomogeneous design overcomes the traditional narrowband constraint of plasmonic systems and thus ensures a wideband response from visible to *** study provides a promising approach to develop next-generation IR PE detectors with ultrafast and broadband responses.
