"The Spirit of the Resting Snowflake" - by Skizit

The CAHT Newsletter is taking a vacation in June
Left:  "The Spirit of Collaboration" by Skizit
Hi folks,
We are working on several major projects which require quite a bit of time and attention and resources, so we are taking a break from the newsletter for June.
Thank you for all your support. When we return on July 1, 2018, or perhaps before, we will announce the launch of the new projects.
Thank you all who have donated so that these projects can be accomplished.  It cannot be done without you.  THANK YOU!

Energy Harvesting Based Body Area Networks for Smart Health
Body area networks (BANs) are small wireless sensor networks (WSNs) which support a lot of medical applications and provide a solution for smart health monitoring [1]. For an exhaustive introduction to BANs, we refer the reader to [2,3]. BANs are configured with ultra-low power consumption wearable devices [4] and medical sensors [5] (such as digestible medical electronics).
These sensors constantly monitor physiological signals and movement data of the human body; they transfer such signals and data to the cloud for analysis, thus realizing intelligent monitoring of the user’s health [6,7].
However, data collection and transfer of BAN sensors consume energy. To increase the comfort of wearable devices, the battery of wearable devices is usually small, thus the battery’s capacity is limited [8,9]. Old batteries need to be replaced frequently or recharged regularly. For medical sensors (such as digestible sensors), it is impossible to replace or recharge the battery. Thus, minimizing energy consumption of wearable devices and optimizing BAN energy efficiency is still a challenging problem [10].
Generally, energy in the BAN sensor can be harvested in the following three ways:
o   Energy harvesting through the environment: some sensors harvest energy through renewable energy sources (including solar, wind, and luminous energy resources).
o   Energy harvesting through the human body: some sensors harvest energy from their own heat energy, bio-energy, body surface friction and body movement.
o   Energy harvesting through a wireless signal: some sensors harvest energy by acquiring wireless signals.
Backpacks could contain lunch, books, drug deliveries, or maybe a mini-cell tower transmitter which communicates or gathers data from the medical implants, RFID chips of the people in the houses they are passing, OR it could contain a battery charger which powers or stimulates the implants or transmitter in or on the house.  Hmmm. Anyone up for a citizen query?
