Market demand for low-power miniature electronics is increasing rapidly with long-lasting (>10 years) power sources required for implantable electronic medical devices (such as neurostimulators to alleviate the effects of Parkinson's disease) and miniaturised sensors e.g. for structural health monitoring in inaccessible and extreme environments. Li-ion batteries have revolutionised portable electronics, but they cannot always meet the environmental, energy density or battery life requirements for some of the most demanding applications. Semiconductor devices for betavoltaic energy generation (the direct conversion of energy from beta particles emitted from radioisotope sources to electricity) can overcome these problems, but existing betavoltaic technology suffers limitations; the devices either suffer from poor efficiency when used with desirable and safe low energy beta emitters such as Tritium, or employ complex designs and structures which are difficult to mass produce commercially. This project will capitalise on previous STFC funded radiation detector research to develop new betavoltaic batteries which overcome the limitations associated with existing betavoltaics and are suitable for a wide range of commercial and scientific applications. Alongside the scientific development, a major component of this project is the development of a commercialisation plan for the technology in order to fully realise the benefits of the work and enable the rapid commercial and scientific exploitation of the technology.

市场对低功率微型电子产品的需求正在迅速增长，可植入电子医疗设备（如神经刺激器，以减轻帕金森氏病的影响）和集成传感器（如用于在难以接近和极端环境中进行结构健康监测）所需的长期（>10年）电源。锂离子电池已经彻底改变了便携式电子产品，但它们并不能总是满足一些最苛刻应用的环境，能量密度或电池寿命要求。用于β伏打能量产生（将来自放射性同位素源发射的β粒子的能量直接转换为电）的半导体器件可以克服这些问题，但是现有的β伏打技术受到限制;这些器件或者在与期望的和安全的低能量β发射体（例如氚）一起使用时效率差，或者采用难以商业化大规模生产的复杂设计和结构。该项目将利用先前STFC资助的辐射探测器研究，开发新的β伏打电池，克服现有β伏打电池的局限性，适用于广泛的商业和科学应用。除了科学发展外，该项目的一个主要组成部分是为该技术制定商业化计划，以充分实现工作的好处，并使该技术能够快速进行商业和科学开发。
