Power constraints play a key role in designing
Human Area Networks (HANs) for biomonitoring. To alleviate
the power constraints, we advocate a design that uses an asynchronous time encoding mechanisms for representing biomonitoring information and the skin surface as the communication
channel. Time encoding does not require a clock while allows
perfect signal recovery; the communication channel is operated
below 1 MHz. We (i) review the fundamental theory behind time
encoding and signal recovery, (ii) describe the implementation of
a HAN prototype and (iii) present research data obtained from
our experimental platform. We demonstrate that the fidelity of
the proposed signal representation and transmission scheme is
well above the biomedical monitoring requirements even in the
case of additive channel-noise and neighboring channel interference. Consequently, the traditional HAN architecture consisting
of clocked A/D converters feeding into digital RF channels can
be replaced with a less power demanding time encoding/decoding
pair that uses the skin surface as a communications channel
