Harnessing biosignals for the future

PHYTL SIGNS RESEARCHER

Designed to allow researchers to explore bio-signals in plants at lo­wer cost, for longer periods and in a wide range of environments. Sophisticated long-term recording and digital signal processing that works with or without a faraday cage.

Electrical signalling is a rapidly growing field in plant research.  But measuring signals reliably and for extended periods requires sophisticated amplification, high-performance analogue to digital electronics, fast data acquisition and storage and complex digital signal processing.  In most cases faraday cages are used to improve signal to noise ratios.

Vivent, the biosignal specialist, is currently packaging the technologies required to measure plant signalling in order to provide a solution that allows long term recording and analysis that can be used with or without a faraday cage.  All the necessary electrodes, amplifiers, filters, disk storage and signal monitoring and analysis tools are included.  The solution is designed for use both in the lab and in the field.

  • Complete electrical signal solution in a box
  • Long term recording
  • Indoors/Outdoors
  • With or without radio frequency shielding chamber

Until now plant bio-signals could only be measured in highly artificial conditions and generally over short periods.  Now Vivent has used innovative electronic and computing technology to allow monitoring and recording of plant signals over extended periods in a wide variety of environments.  Vivent is the world leader in developing equipment for harnessing the `internet of plants ‘ and is developing pioneering bio-signal technology for laboratories, professional plant growers, plant lovers and students.

Phytl Signs Researcher is designed to aid scientific enquiry into plant electrical signalling.  The system brings together technologies needed to accurately and reproducibly record electrical signals from plants.  The system includes electrodes, amplifiers, filters, A to D (analogue to digital) processors, storage facilities and digital signal processing tools.

This package of technologies is designed to be usable out of the box but is also flexible enough that it can be customised and modified at any stage.  The system can be set up to provide live feedback, including audible warnings of specific plant events and to record the long term history of signals over days, weeks or even months.   Vivent’s systems are designed using the latest technology in integrated circuits, embedded device technology and DSP (digital signal processing) to provide plant researchers with a reasonably priced package which allows them to focus on their plants and experiments rather than the IT (information technology).

The Vivent system also has the objective of allowing experiments in a far wider range of environments and over a more extended period that has been the case for most laboratories so far.

At the core of Phytl Signs Researcher is a Linux computer with a built in data capture card. Also included in the package are the amplifiers and filters necessary to condition the plant signal prior to digitisation. A high speed hard drive captures the information in a highly customisable format. As data is recorded customized software constantly analyses the signal to see if there is something specific that needs to be captured in great detail, or, if the signals in a given time period can be regarded as steady state in which case the data can be compressed. In this way a huge period of time can be recorded without the need for very large storage capacity. The information recorded is presented in a summarized form allowing the researcher to go into greater detail at any point.

Phytl Signs Researcher is designed for use in laboratory conditions but it would be equally at home in a research glass house. For use outdoors Vivent has a range of weather-proof data collection devices that can be used in conjunction with the standard model.

For strong clear signals there is little doubt that experiments conducted in clean RF environments provided by a Faraday cage produce the best results. It’s a question of managing the signal to noise ratio. With an in-depth knowledge of signal levels in plants, and extremely skilled signal processing management Vivent is able to engineer a solution that filters out noise to produce acceptable signals even outside the chamber.

Vivent’s professional services division can provide advice on your specific needs as a researcher. We can measure how much noise there is in your particular environment and advise on how to set up your experiment using our equipment. We expect this service to be available in mid 2017.
