SENSOR-ENABLED DIGITAL HEALTH
A WINDOW ON
In evaluating therapy effectiveness, physicians and staff must often make decisions on the basis of periodic "snapshots" of key indicators taken during testing in the doctor's office or lab, typically during daytime hours.
Yet diseases are dynamic -- patient markers can fluctuate over 24 hours, with significant peaks and valleys never reflected in static testing. Our ultra-miniature sensor platform with solid-state microbattery continuously and remotely monitors physiological parameters 24/7 over years, with programmable sampling from milliseconds to hours.
The device can be customized to provide physicians with both a pre-treatment patient baseline for key indicators including pressure, flow and oxygenation. Once treatment begins, it offers continuous visibility into therapy effectiveness, including drug latency and effects of multi-drug interactions on the designated parameters.
INJECTSENSE SENSOR MODULE
Our sensor module consists of a pressure sensor, an IC with power management, a solid-state micro battery, and wireless communications technology.
The integrated sensor platform is hermetically sealed so there is no contact between the electronics and fluids or tissue in the body. It fits into a custom carrier designed for each application, or can be embedded in an existing product.

SOLID-STATE RECHARGEABLE MICROBATTERY
The key to autonomous sensing
Power and size constraints limit most implantable sensors to on-demand sampling by a physician, or by patient themselves. This measurement generates only a static daytime "snapshot" that cannot accurately track the peaks and valleys of physiological indicators over a 24 hour period.
A truly autonomous , 24/7 ultra-miniature sensor requires an energy-dense, rechargeable microbattery in the smallest possible form factor. Injectsense's use of the Injectpower solid-state microbattery in its implantable sensor platform enables continuous measurement over decades and the capability of sampling at intervals of seconds, minutes, or hours, including during sleep. The battery is recharged once a week using a wearable receiver such as smart glasses -- a process of a few minutes.
HOW THE PLATFORM WORKS
The autonomous implant collects data at physician-specified intervals. Once a week the patient uploads data securely to a wearable receiver (such as smart glasses) worn for a few minutes, which also recharges the sensor.
The encrypted data is transmitted from the wearable to the patient's smartphone and then to the cloud. The system remotely alerts the physician to any anomalies.
LEVERAGING WAFER SCALE QUALITY
The Injectsense sensor platform is highly versatile, permitting measurement of multiple physiological parameters including pressure, flow, oxygenation, and motion. As an advanced integrated semiconductor device, the platform integrates microelectro-mechanical systems (MEMS), application-specific ICs (ASICs), a microbattery, and wireless technology.
Injectsense engineers leverage the latest technologies from Silicon Valley's chip industry to manufacture high-quality wafers that meet exacting medical standards. Injectsense incorporates design for test (DFT) and design for manufacture (DFM) techniques in developing its sensors, as well as Failure Mode and Effect Analysis (FMEA) to evaluate production process results.
