The growing demand of portable electronic devices has created the demand of long lasting recharged source of power. Non-environmental friendly conventional batteries with limited lifetimes are no longer a feasible option. This paper proposes a piezoelectric, vibration based energy harvester. The design and simulation of a MEMS piezoelectric cantilever beam with interdigitated electrodes is described...
We report the deposition and characterization of thin ZnO films on 〈100〉 silicon substrates employing Atomic layer deposition (ALD). This technique is considered to have a great potential for nano-scale applications due to its excellent conformality, total surface coverage, uniformity, accurate thickness control, its ability to deposit high k-dielectrics, metals, nucleation layers and barrier materials,...
In this work, phase shifting performance of atomic layer deposited (ALD) films and ferroelectric films had been measured on flexible substrates. ALD ZnO and PVDF/TrFe films were patterned on signal electrode of coplanar waveguide, and their phase shifting performance was collected with a Vector Network Analyzer (VNA) in combination with coplanar microwave probes between 1 GHz to 50GHz.
Zinc oxide thin films are becoming increasingly popular for their wide range of properties and the ability to deposit these films on organic substrates for applications such as biotemplating, OLEDs, or deposition on fabrics for functionalization purposes including power generation from the flexing and deformation of wearable textiles. However, since many fabrics and other organic substrates can not...
