壓電感應的應用由於近年來能源即將浩劫，再生能源形成一種熱潮，平時許多人

壓電感應的應用由於近年來能源即將浩劫，再生能源形成一種熱潮，平時許多人都煩忙於工作，白天幾乎沒有時間運動，「夜跑」越來越興盛，但是在夜間跑步時可能有時候會沒有路燈，晚上燈光不足，汽車駕駛可能會沒看到我們，而且近年來綠能蓬勃發展，因此我們想做一個自動發電、發光夜跑鞋！在參加這個科展之前 我們有先參考去年科展的冠軍作品-----利用半導體溫差發電晶片 運用「體熱」發電 我們覺得這個東西的潛能無窮 因此我們想要利用這個半導體溫差晶片並且搭配「壓電片」使鞋子走路也能發電！ 發電片是什麼呢? 其實她的種類有兩種 而我們使用的是當晶體受到某固定方向外力的作用時，內部產生電極化現象，同時在某兩個表面上產生符號相反的電荷；當外力撤去後，晶體又恢復到不帶電的狀態；當外力作用方向改變時，電荷的極性也隨之改變我們想利用走路時對鞋子產生的壓力並施加在壓電片上產生交流電並且透過整流器轉換成直流電使裝在鞋子上的LED燈泡發光 但體重產生的壓力主要是在後腳跟 而前中段部分的壓力較小 所以我們想利用穿襪子時的熱溫差 配合半導體溫差發電晶片發電 而半導體溫差發電晶片又是什麼呢 ? 以P型半導體材料為例，在有溫差的狀態下，熱端的多數載子（電洞）有較大的機率由熱端往冷端移動，整體表現如同電流由熱端流向冷端；同理，N型半導體上的多數載子（電子）也是一樣的狀況，當這一對P型及N型半導體材料以導電材料將其串接後，整體迴路形成電流。簡單來說：利用溫差控制電子及電洞移動的方向，進而形成電流，此即溫差發電原理 而且半導體溫差發電晶片價格便宜 因此我們想要運用這個溫差發電晶片及壓電片裝在鞋子上發電 製造出一個發光夜跑鞋！

The piezoelectric sensing applications
in recent years energy coming catastrophe, the formation of a renewable energy boom, many people are tired of the usual busy with work, almost no time for exercise during the day, "night run" more and more prosperous, but may sometimes while running at night no street lights, insufficient lighting at night, motorists may not see us, but in recent years the booming green energy, so we want to do an automatic power generation, LED night running shoes! Before participating in the science fair that we have to refer to last year's science fair prize winner ----- temperature difference power generation using a semiconductor wafer using "body heat" We feel the potential power of this thing infinite and therefore we want to take advantage of the temperature difference between the semiconductor wafer and match "piezoelectric film" walk the shoes can also generate electricity! ? What power is it really her piece, there are two species that we use are subject to certain fixed when the crystal orientation of the role of external forces, internal electric polarization phenomenon, but have the opposite sign of charge on a surface of two; when an external force upon withdrawal, the crystal has returned to an uncharged state; when the external force changes direction, the polarity of the charge also changes when we want to use the pressure of walking shoes generating and applying an alternating current is generated on the piezoelectric sheet via the rectifier into a direct current and the LED light bulb mounted on the shoe body but the pressure generated mainly in the middle part of the heel of the pressure front therefore we want to use a smaller temperature difference at the heat socks with semiconductor thermoelectric power generation wafer and the semiconductor wafer is thermoelectric power generation What is it?
P-type semiconductor material, for example, in a state where the temperature difference, the majority carriers (holes) of the hot end of a larger chance to move by the end of the cold end of the heat, the overall performance of heat as current flows from the cold end side ; Similarly, majority carriers (electrons) in the N-type semiconductor is the same situation, when the P-type and N-type semiconductor material After a conductive material which serially connected, integrally formed loop current. In simple terms: the use of electronic temperature control and direction of the hole mobility, and thus the formation of the current, namely the principle of thermoelectric power and thermal power generation semiconductor wafers are cheap so we want to use the thermoelectric power generation chip and the piezoelectric film equipment in power generation manufacturing shoes a luminous night running shoes!

Application of piezoelectric induction
In recent years, energy is going to be a disaster, and renewable energy has become a boom. Usually, many people are busy with their work. During the day, they have little time to exercise, and "night running" is becoming more and more prosperous. However, during night running, there may be no streetlights, and at night, the lights are not enough. Driving cars may not see us, and in recent years, green energy has flourished. Therefore, we want to be a self starter Power generation, luminous night running shoes! Before participating in this science exhibition, we first referred to the champion work of last year's science exhibition - using semiconductor thermoelectric power generation chip to generate electricity with "body heat". We think the potential of this thing is infinite. Therefore, we want to use this semiconductor thermoelectric chip and match it with "piezoelectric chip" so that shoes can generate electricity when walking! What's the type of generator? In fact, there are two kinds of generator. What we use is that when the crystal is affected by an external force in a fixed direction, there will be an electrode phenomenon inside, and at the same time, there will be a charge with opposite sign on two surfaces. When the external force is removed, the crystal will return to a state without electricity. When the direction of the external force is changed, the polarity of the charge will change accordingly. We want to make use of it When walking, the pressure on the shoes is applied to the piezoelectric chip to generate alternating current, which is converted into direct current through the rectifier to make the LED bulb installed on the shoes glow, but the pressure generated by the weight is mainly the pressure in the rear heel and the front middle part is relatively small, so we want to use the thermal temperature difference when wearing socks to cooperate with the semiconductor thermoelectric power generation chip to generate electricity, while the semiconductor thermoelectric power generation chip What is it?
Taking p-type semiconductor materials as an example, in the state of temperature difference, most carriers (holes) at the hot end have a greater probability of moving from the hot end to the cold end, which behaves as the current flows from the hot end to the cold end as a whole; similarly, most carriers (electrons) on n-type semiconductor are also in the same state. When the p-type and n-type semiconductor materials are connected in series with conductive materials, the overall circuit is formed Current. To put it simply: use the temperature difference to control the direction of electrons and holes, and then form the current. This is the principle of thermoelectric power generation, and the semiconductor thermoelectric power generation chip is cheap, so we want to use this thermoelectric power generation chip and piezoelectric chip to generate electricity on shoes to create a light generating night running shoe!
