In the past few weeks the housing for the seizure watch was designed and 3D printed as a prototype. The focus currently is on how the electrodes for detecting electrodermal activity will be placed on the wrist and how the electrodes’ wires will be running on the straps of the watch.

A highly accurate electrodermal activity signal, within a precise frequency range and voltage level, is obtained by developing a simple circuit for analog pre-processing [1]. This circuitry is used to limit the current to the electrodes to a safe amount, measure the resistance between the electrodes, and amplify the signal for input to the ADC of the BTLC1000 chip.

The digital temperature sensor DS18B20 was selected based on the level 1 and level 2 requirements of the project: weight, accuracy, and safety. The sensor is waterproof and therefore safe for a child who sweats during play. This blog post focuses on the initial testing and implementation of the sensor.

For the electrocardiogram (ECG) demonstration, the group was required to generate a real-time ECG signal from a subject and transmit the signal to over to the Arxterra website either on a phone application or a computer through Bluetooth. The following is the process taken in order to develop the ECG circuit and develop communication both from the Bluetooth module to the phone and from the phone to the Arxterra app.

The purpose of this experimentation was to identify example applications for the ATBTLC1000 and determine which parts might be useful for software program subroutines. The example code used is also provided.

This document will discuss the individual thought process behind the selection of each sensor to be used for the A-TeChToP Project. This will include trade-off studies, sensor quality comparisons, and sensor price comparisons. Ultimately, each sensor picked will be done so with the intention of utilizing it within the project’s final design.
