Description(English)	Globally, many with severe hearing loss rely on cochlear implants. High costs, maintenance, and frequent disposable battery replacements burden families and harm the environment. iHEAR self-generating cochlear implant uses liquid metal magnetohydrodynamic technology. Its external battery converts mechanical energy from liquid metal movement during activity into electricity, continuously powering the implant and storing excess energy for stationary use. This reduces battery pollution, eases financial strain, and ensures stable operation, providing an affordable and reliable solution.
Description(Native)	全球约2.5亿重度以上听力损失患者需借助人工耳蜗重获听力，然而人工耳蜗价格昂贵，后期保养与频繁更换一次性电池带来的经济压力、环境污染问题，困扰着无数家庭。即便政府为部分贫困家庭儿童提供免费植入政策，其后续电池使用成本与设备突然断电风险，仍是亟待解决的难题。 针对这些困境，iHEAR自发电人工耳蜗创新性地搭载液态金属磁流体发电技术。其外机内置的液态金属磁流体发电电池，可将人体运动时液态金属晃动切割磁感线产生的机械能，高效转化为电能，为人工耳蜗持续供电。多余电能还能储存，确保人体静止时设备也能正常运转，实现永续供电。这种清洁可持续的供能方式，不仅减少废弃电池对环境的污染，还大幅降低家庭长期购买电池的经济支出，以更低成本、更安全稳定的保障，助力重度听力损失患者聆听世界。
Positive Comments
Judging Comments	The iHEAR cochlear implant introduces self-generating power using liquid metal magnetohydrodynamic technology. By converting movement into electricity, it continuously charges the device and stores excess energy for later use. This innovation reduces disposable battery waste, lowers costs, and provides a stable, reliable solution for people with severe hearing loss.
