Wearable and ingestible sensors are revolutionising the health monitoring space as the demand for quality healthcare continues to rise. Emphasis on preventive health has led to the development of prognostic sensors for applications in the medical industry. This, in turn, has led to a shift in the healthcare business model from a diagnostic one to more prognostic and preventive health and wellness. 
 
Sensor adoption is crucial to this evolution, facilitating advanced diagnostics, treatment and patient monitoring. Wearable and implantable biosensors will emerge as the key enablers for device innovation.
“The Internet of Medical Things will lead to sensors playing a greater role in offering connected healthcare infrastructure,” said Measurement and Instrumentation Industry Principal Dr. Rajender Thusu. “However, there are no clear policies or standardisations yet that companies can adhere to while implementing the connected health platform. The greatest challenge, therefore, lies in bringing together different applications under the same working platform, when individual solutions lack interoperability.”
"Or even less appealing, the state of this patient could be so severe, that they require full time skilled nursing care in the confines of a nursing home or assisted living facility.
“you could take a device and instead of the patient wearing it on his or her wrist or clothes, a physician implants that device in the chest”
Imagine much like a FitBit, you could take a device and instead of the patient wearing it on his or her wrist or clothes, a physician implants that device in the chest. That device then has wires that run underneath the skin to various nerves in the body and to the deep parts of the brain. That device can then send specific amounts of electricity to the nervous system at various times to disrupt the diseased pathway and restore the patient to normal health. "
