Abstract
Internet of Things (IoT) has gradually evolved to take the centre stage of the consumer technology market with an astounding projected
market size of $520 Bn by 2021*. Although the potential market volume grabs the eyeballs easily, the product types have not kept pace
until recently, with the market being comprised of the same basic products like smart watches, health and fitness trackers, cameras,
headsets and smart glasses.
Conditions, however, are ripe for the next evolution in IoT with the advent of smart clothing (e.g. self-tying shoelaces, temperature-
regulating fabric), bio-wearables (e.g. smart contact lenses) and, most importantly, “Swallowables” or Ingestible IoTs. The recent FDA
approval of digital pills / swallowable sensors has given further boost to this technology, which we expect to garner ~ $8 Bn in IoT
services revenue by 2026. This is too large a pie to be ignored and hence charting out the right Quality Assurance strategy for
swallowables is of utmost importance.
Our paper analyzes the swallowables ecosystem and identifies 5 representative layers, viz. Device (ingestible + wearable), Patient
Smartphone App, Gateway, Cloud Platform & Physician / Caregiver App. Further, a comprehensive QA strategy for the entire ecosystem
has been charted out and the QA needs for each layer have been identified. The paper also delves deep into each of these types of testing
and proposes a test orchestration process to showcase how the entire gamut of testing can be performed for a typical business flow.

Swallowables - Context & Overview
• Internet of Things (IoT) has revolutionized virtually every industry – global
market size projected to be $ 1.9 tn by 2020*
• Amidst concerns around safety, efficacy & ethics, Abilify Mycite became the
first digital pill to receive US FDA approval in 2017
• Recently, the “Swallowables”, i.e. Ingestible IoTs have
complemented the “Wearables”
o Pills with embedded sensors, when swallowed,
collect critical data and transmit to patient
smartphone apps via BLE protocol, which further
shares the same with the physician / caregiver app
/ portal over internet
o This data is leveraged in multiple ways by physicians, family members &
care-givers for remote patient management
