英文摘要	The tropical desert plant (aloe-vera, AV) derived natural bio-organic material used to convert the waste mechanical energy into electrical energy. The piezoelectric force microscopy measurement of AV film shows the amplitude resembles the butterfly-like shaped, and the phase loop depicts the 180 degrees switching of domains confirming the ferroelectricity of AV. The obtained converse piezoelectric coefficient (d(33)) is 6.5 pm V-1, and remnant polarization is 1.02 mu C/cm(2) for poled AV film due to the development of long-range order of acemannan (A) chains and their interaction between them A-A or A-uronic acids through the newly formed hydrogen bonds. The piezoelectric AV film-energy harvester (AV film-EH) generates a peak-to-peak output response of (1.2 V, 200 nA), and the instantaneous peak power is approximate to 0.42 mu W at 10 M Omega upon 4 N force. The non-contact surface potential measurement and KPFM results confirm the AV is a moderate positive triboelectric material having a surface potential of +1.14 V, respectively. The triboelectricity of AV explored in two approaches, such as dry film (F) and gel (G) type interacting with the different materials. The AV film-PDMS, AV gel-PDMS TENG, delivers an instantaneous power density of 0.19 mu W/cm(2) upon 2 m/s(2) acceleration of shaft load and 0.22 mu W/cm(2) upon biomechanical hand force. Next, successfully demonstrated the AV film-EH could work as a self-powered finger monitoring sensor to monitor human finger bending angles. It also explored that the electrical output of AV filmPDMS TENG is used to power the smartwatch successfully. Here, the generated electric energy from the desert plant is clean, cost-effective, and plentiful to develop the self-powered biosensor/implantable devices.
