- Wireless transmission medical device with a plurality of brainwave collection sensors of multichannel ECoG electrodes using F-TFTA for brain disease treatment

摘要

Disclosed is a wireless transceiving medical device having multi-channel ECoG electrodes using an F-TFTA and brainwave collection sensors for a brain disease treatment. The medical device comprises: an F-TFTA arranged in an active matrix structure having ECoG electrodes including a TFT and a brainwave collection sensor for each pixel on a flexible substrate, and a neural stimulator, and a DDIC connected to the F-TFTA; an ECoG detection system having a control unit, a storage unit and a wireless communications unit connected to the DDIC, and transmitting ECoG signals of a multi-channel using wireless communications through parallel processing by measuring voltage and current (I_DS) of the TFT of an ECoG electrode of each channel; and a user terminal having the wireless communications unit, the control unit, the storage unit and an LCD display unit for receiving ECoG signals of the multi-channel from the ECoG detection system, outputting brainwave data for each channel after brainwave signal processing, finding out an epilepsy occurring part by detecting abnormal brain waves causing epilepsy by brainwave analysis, and controlling a neural stimulation treatment by driving the neural stimulator of the epilepsy occurring part by deep brain stimulation for a pixel of a position and a range of an epilepsy lesion.
