Promwad EEG Biosensors Electroencephalography

Promwad started in 2017 researches in the development area of devices based on EEG sensors for consumer devices. This technology allows to read out electric activity of different areas of a brain and to create new devices and programs with neurointerfaces for virtual reality, training, medicine and the sphere of entertainments.

The electroencephalography (EEG) was used in medicine from the first half of the 20th century, but the first low-consuming EEG-sensors which could be used in consumer electronics for wide audience of nonprofessionals began to appear about ten years ago. So there was a new market of devices based on EEG biosensors.

Engineers of Promwad became interested in this technology and started the first project on development of a prototype of the device based on EEG sensors. The new device will keep track of wave activity of a brain of the person in household premises at a large number of electronic devices which create low-frequency noises. Now software engineers of the company develop the software for training and control of any devices.

Promwad uses EEG-sensors with dry electrodes which can be used without contact conducting medium of type of gel or physical solution. The device with sensors is created in the form of the headset; its software processes data of measurements and sends them through Bluetooth to the user device — phone, the tablet, the computer — or to "cloud" where data can be used for work of different applications through API.

Development process of devices based on EEG-sensors considerably became simpler since the design centers got access to ready hardware-software platforms and debug payments for measurement of wave activity of a brain and display of results worldwide in real time. They create devices and the programs capable to interpret data of measurements as binary values "yes" and "no". Users of such devices receive a feedback about the psychoemotional status in the form of the simplest diagrams and quickly enough learn to affect results of measurements, consciously changing the status, receiving the necessary values "yes" or "no". This opportunity allows engineers to create algorithms for control of any electronic devices with connection to the Internet: from simple algorithms for switching of channels in the TV "by force of thought" before difficult settings in electronics for bionic prostheses, wheelchairs and also for the most different games, attractions of virtual reality and children's toys.

Potential scope of EEG-sensors includes "live toys", the computer or mobile games reacting to activity of a brain of the person; interactive cinema where the plot of the movie depends on mood of the viewer, contextual advertizing and marketing researches which monitor reaction of clients to the price of products and services; communication devices and robotic extremities for disabled people, devices and exercise machines for training and professional training.
