Researchers at the National Oceanography Centre, Southampton, and at the School of Electronics and Computer Science at the University of Southampton have collaborated to produce a low power, small conductivity and temperature (CT) sensor system for high accuracy ocean salinity monitoring. These miniaturised devices use microfabrication techniques similar to those used to manufacture integrated circuits out of semiconductor materials. The conductivity sensor contains several electrodes and a water channel for immersion application. The temperature sensor is based on an electric bridge of platinum resistance thermometers (PRTs). Several high accuracy salinity sensors are commercially available, but they are all large and expensive. Smaller systems have been developed but they are inaccurate. Our current prototype is the size of a 1.5L pot, using 7-electrode and a 2x2 mm water channel for conductivity measurement. A circuit based on trans-impedance amplifiers and FPGA is used to drive the CT sensor and log the data. The sensor system can work for more than one month powered by a PP3 battery. The next generation will use a 4-electrode cell without water channel for conductivity measurement. By integrating all the control circuit into an ASIC, the sensor system can be packaged in a device that will allow use as a high accuracy data logging fish tag. The proposed activity will evaluate if this technology has commercial potential (i.e. can industry make money out of this) and will identify the first steps of a plan to maximise the income generated by this idea. This will include an evaluation of the market for the sensor technology; a review of patents and opportunities for protection of the idea; and evaluating possible partners and initiating contacts with them. CT values not only can be used for salinity calculation, but also are the key parameters for most chemistry sensors. So CT sensing is required by a number of industries (e.g. agriculture, aquaculture, water treatment industries, and offshore industries) and by scientists (e.g. in oceanography, in the study of fresh water systems, and in plant research). We are therefore, hopeful that this idea could have significant market potential and could contribute to the competitiveness of UK industry.

南安普敦国家海洋学中心以及南安普敦大学电子与计算机科学学院的研究人员合作生产低功率，较小的电导率和温度（CT）传感器系统，以高精度海洋盐度监测。这些微型设备使用的微加工技术类似于用半导体材料制造集成电路的微型设备。电导率传感器包含多个电极和一个用于浸入浸水的水通道。温度传感器基于铂电温度计（PRTS）的电桥。商业上有几种高精度盐度传感器，但它们都大而昂贵。已经开发了较小的系统，但它们不准确。我们当前的原型是使用7电极和2x2 mm水通道进行电导率测量的1.5L锅的大小。基于反向阻抗放大器和FPGA的电路用于驱动CT传感器并记录数据。传感器系统可以使用PP3电池供电超过一个月。下一代将使用没有水通道的4电池电池进行电导率测量。通过将所有控制电路集成到ASIC中，可以将传感器系统包装在设备中，该设备将允许用作高精度数据记录鱼标签。拟议的活动将评估该技术是否具有商业潜力（即行业可以从中赚钱），并将确定计划的第一步，以最大程度地利用该想法产生的收入。这将包括对传感器技术市场的评估；审查专利和保护想法的机会；并评估可能的合作伙伴并与他们建立联系。 CT值不仅可以用于盐度计算，而且是大多数化学传感器的关键参数。因此，许多行业（例如农业，水产养殖，水处理行业和近海行业）以及科学家（例如海洋学，淡水系统研究以及植物研究中）所需的CT传感。因此，我们希望这个想法能够具有巨大的市场潜力，并可以为英国工业的竞争力做出贡献。
