摘要： A propellant flow actuated piezoelectric igniter device using one or more hammer balls retained by one or more magnets, or other retaining method, until sufficient fluid pressure is achieved in one or more charging chambers to release and accelerate the hammer ball, such that it impacts a piezoelectric crystal to produce an ignition spark. Certain preferred embodiments provide a means for repetitively capturing and releasing the hammer ball after it impacts one or more piezoelectric crystals, thereby oscillating and producing multiple, repetitive ignition sparks. Furthermore, an embodiment is presented for which oscillation of the hammer ball and repetitive impact to the piezoelectric crystal is maintained without the need for a magnet or other retaining mechanism to achieve this oscillating impact process.

摘要： The present invention discloses an apparatus and a process of using the apparatus to generate an electric energy in a crowded place. The apparatus comprises of an array of nanogenerators with a novel composition in a mesh of nanowires specifically piezoelectric nanowires embedded in a thin and transparent tape that may be paste/stick on a floor in a crowded place or a place with heavy traffic. The apparatus generates an electric field by using variations in pressure and surface temperature which is then transferred to a charging/discharging board in the form of an electric energy for later use.

摘要： A power generating device includes a first casing, a magnetic component, a second casing, an induction coil, and a first piezoelectric device. The first casing and the second casing engage with each other to form a space, and the magnetic component is fixed on the first casing and configured in the space. The induction coil is fixed on the second casing and configured in the space, and it is positioned outside the contour of the magnetic component. The first piezoelectric is configured between the magnetic component and the first casing. When an external force acts on the first casing and the second casing, the first casing and the second casing move relatively to each other so that the induction coil generates an induced current by sensing a magnetic flux variation, and the first piezoelectric component generates a first charge by absorbing the pressure between the magnetic component and the second casing.
