研究组将区域水资源可用性作为限制因素，揭示了32种开采地质资源的全球生产能力。他们发现，目前的资源开采大大超过了区域水资源限制，特别是2010年的铜开采（当前产量的37%超过了可用的水资源容量）。将生产地点转移到水资源压力较小的地区将缓解目前超出水资源限制的情况；然而考虑到经济因素，这并不现实。

Piezoelectricity — perhaps one of the most underrated technologies ever developed. You use it every time you turn on your stove and it is the thing that keeps your quartz watch tracking time.

半Heusler窄带隙半导体中的压电效应能量收集技术可以让电子设备自供电，而压电材料（PE）通过机械应力产生电压，将振动能量转化为电能。PE材料的性能由PE应变系数d决定，较高的d值表示更强的PE性能。PE材料研究主要集中在陶瓷和宽带隙半导体材料上， ...
