PiEEG na'ura ce don mai araha amma ingantaccen mai karanta siginar halittu na kwakwalwa
Ildar Rakhmatulin, mai bincike a Kwalejin Imperial da ke Burtaniya, ya ƙera na'ura que yana juya Rasberi Pi zuwa ƙirar kwakwalwa da kwamfuta
Wannan na'urar da ake kira PiEEG, ƙarin tsari ne wanda ke haɗi zuwa Rasberi Pi. Kamar sauran electroencephalography (EEG), electromyography (EMG) da electrocardiography (ECG), PiEEG zai iya auna siginar lantarki daga kwakwalwa kuma ya kara fassara waɗanda aka karɓa.
Cewar Rakhmatulin, An fara wannan aikin saboda ya lura cewa sha'awar neuroscience ya karu a tsawon shekaru. Da farko, Rakhmatulin ya ƙirƙiro wata karamar kwamfuta mai ɗaukar hoto mai ɗaukar hoto. Bisa ga bayanin da mai binciken ya yi, wannan ƙayyadaddun kayan aikin EEG wanda ke da siffar madauwari da radius na 25 mm kawai ya ba da damar yin amfani da yau da kullum dare da rana.
da za a aika bayanan da na'urar ta tattara zuwa uwar garken sirri ta amfani da ka'idar TCP-IP, bada izinin aiki mara waya da ingantaccen kewayon motsi ga mai amfani. Wannan samfurin na farko kuma yana da ginanniyar ƙarfin hana amo don inganta daidaiton rikodin tare da matsakaicin ƙarar shigar da ƙasa da 0,35 μV.
bayan zane, jimlar farashin wannan ƙirar ta farko ta kasance kusan $350 don wayoyin lantarki 24. Amma karancin guntu wanda ya faru tsakanin 2020 da 2021 ya kara farashin na'urar sosai. Don kada ya watsar da aikin nasa, mai binciken ya yanke shawarar ƙaddamar da sigar na biyu na ƙirar kwakwalwar kwamfuta da kwamfuta, amma a wannan lokacin bisa ga Raspberry Pi, wanda ya ba da damar aiki mara waya da kuma yanayin motsi mai kyau ga mai amfani.
An yi zaɓin Rasberi Pi saboda a cewar Rakhmatulin, ita ce mafi shaharar kwamfutoci guda daya a kasuwa, kuma hanya mafi sauki ta fara daukar matakin farko a fannin kimiyyar kwakwalwa. Don wannan karo na biyu, mai binciken ya bayyana cewa ana iya samun garkuwar ta amfani da Raspberry Pi 3 ko 4, wanda farashinsa bai wuce $100 ba. Saboda haka, yana da arha kuma mai sauƙin kulawa.
Haɗe da plugin ɗin, PiEEG zai kashe tsakanin $250 da $350 tare da fasali masu zuwa:
- Mai jituwa tare da Rasberi Pi 3 ko 4
- Tashoshi 8 don haɗa jika ko busassun lantarki
- Canja wurin bayanai ta hanyar ka'idar SPI tare da mitar 250 SPS zuwa 16 kSPS da ƙuduri na 24 ragowa kowane tashoshi.
- Ribar siginar da za a iya aiwatarwa: 1, 2, 4, 6, 8, 12, 24
- Ability don auna impedance
- CMRR Ƙimar Ƙimar Juyi na gama gari: 120
- Amo na ciki: 0,4 μV
- Hayaniyar waje: 0,8 μV
- Sigina zuwa Raba Amo (SNR): 130dB
- LED don nuna wutar lantarki da alamar haɗin ADS1299
- 3 kyauta don haɗa abubuwan waje (ƙasa da tashar Raspberry Pi)
- Ana iya amfani da fil ɗin Rasberi Pi GPIO 33 don ayyuka daban-daban, kamar haɗa na'urorin waje.
- Sauƙaƙan shirye-shirye tare da samar da buɗaɗɗen software don karantawa da sarrafa bayanai a cikin Python, C da C++
Ga masu son samunsa. Kwanan nan an kaddamar da gangamin taron jama'a. Sigar tashoshi 4 na PiEEG shine $ 250 kuma sigar tashoshi 8 shine $ 350.
Rakhmatulin da abokan aikinsa suma sun buga takarda da ke nuna aikinta: Sun sami damar sarrafa linzamin kwamfuta ta hanyar lumshe ido.
"Amma yuwuwar ta fi girma kuma ana iya amfani da na'urar a masana'antu daban-daban, dangane da sha'awa da damar mai amfani," ya rubuta.
Hasali ma, Rakhmatulin ta ruwaito. Ana iya amfani da siginar PiEEG, alal misali, don sarrafa gida mai wayo, wasanni, robotics, shigar da madannai na kama-da-wane, ko ma gwaje-gwajen polygraph na DIY. Na'urar "har ila yau, masu sha'awar koyon na'ura za su iya yin amfani da na'urar don ƙirƙirar ayyukan sarrafa mutum-mutumi da gaɓoɓin injina tare da ikon tunani, sarrafa barci, sarrafa tunani, ko azaman mai gano motsi, gano ƙarya, da ƙari mai yawa," in ji Rakhmatulin.
Labari mai dadi tare da irin waɗannan ayyuka masu sauƙi shine cewa za su iya ƙarin koyo game da kwakwalwa a cikin shekaru 10 masu zuwa fiye da yadda muka koya a cikin 50 na ƙarshe. Matsalar yanzu, duk da haka, zai kasance nemo mutanen da suka yarda cewa kowa zai iya. haɗi zuwa kwakwalwarka. Amma ƙari, ba za a iya cire matsalolin abin duniya ba. Hasali ma dai, an ba da rahoton cewa na’urorin na’urar za su gaji da sauri cikin lokaci, wanda hakan na iya kara tsadar amfani da na’urar. Bugu da ƙari, ya zama dole a nemo hanyar da za a ajiye waɗannan na'urorin lantarki na tsawon lokaci, wanda ba shi da sauƙi a lokacin gwaji.
Amma tuni tare da ikon karanta siginar ƙwaƙwalwa cikin arha da yin ayyuka bisa waɗannan sigina, muhawarar da ake ta cece-kuce kan adana ƙwaƙwalwar ɗan adam akan na'urar ajiya tana sake tashi.
