作者开发了一种新的系统，该系统能够通过婴儿仰卧位从其背部表面穿的内衣检测电图电位，只需将电极放置在内衣下。该系统基于涉及电极、内衣和皮肤的电容耦合，并且还基于阻抗匹配电路以调节耦合的高输出阻抗与后续电路所需的低输入阻抗。对6名43 ~ 136天的婴儿用常规装置进行了同步测量，结果表明，即使婴儿穿着内衣，只要他/她在皮肤-电极耦合处产生足够的压力并在测量期间睡觉，也可以获得与参考ECG同步的周期性波形。
The authors have developed a new system capable of detecting electrographic potential through underwear worn by an infant lying in a supine position from its dorsal surface, simply by placing the electrodes under the underwear. The system is based on capacitive coupling involving the electrode, the underwear, and the skin, and also on an impedance matching circuit to mediate high output impedance of the coupling with low input impedance required by subsequent circuitry. Simultaneous measurements with a conventional device were conducted in 6 infants aged 43 to 136 days, and revealed that periodic waveforms synchronized with the reference ECG could be obtained even when underwear was worn by the infant so far as he/she yielded sufficient pressure at the skin-to-electrode coupling and slept during the measurement.
