wrist strap and a telemedical system are designed based on this fabric, which can collect and analyze heart
rate and pulse data, as shown in Figure 9C.

Since Google Glasses came out, intelligent eyewear devices have been attracting increasing attention. As a
device near the head, eyewear healthcare monitoring devices can monitor more physiological signals.
Homayounfar et al. sewed conductive silver wire on the surface of the hydrophobic and coated a layer of
[179]
AgCl as an ionic interface to collect ophthalmic signals . At the same time, a pressure sensor is formed by
pasting silver-plated nylon fabric on both sides of cotton fabric to collect pulse signals. Based on the above
devices, the bioelectricity pulse monitoring glass is designed to comprehensively monitor the health state of
users.

Clothing is an indispensable part of daily life and a better form of a healthcare monitoring system. Smart
clothing, integrated with various sensors and electronic systems, has a more comprehensive monitoring
range and better-wearing comfort. He et al. coated graphite and lithium cobalt oxide (LCO) slurry on
copper and aluminum wires, respectively, wrapped the two wires and then encapsulated them with
polymers to develop fiber lithium-ion batteries . At the same time, they prepared sweat ion monitoring

fibers by coating Na and Ca selective membrane precursors on Ag/AgCl reference electrodes. Then, they
designed a healthcare monitoring jacket with sensing, display, communication, and energy storage
functions. It can monitor the ion concentration in the user’s sweat in real-time and display the data on the
jacket, while the textile-based battery can ensure its all-day work. Wei et al. presented a graphene-based
