Intelligent Micro-Engineered Electrocardiography Jacket

Description

Contact Supplier

With the financial support from the Innovation and Technology Commission, we have established an ECG jacket embedded with the measurement electronics. This ECG jacket, which appears to be regular clothes, can record the long-term heart status of patients for tele-health care and medical purposes. From the user's perspective, this product has strict requirements on comfort, non-allergenicity and measurement reliability.

Intelligent micro-engineered electrocardiography jacket for long-term monitoring of heart disease.
Heart diseases (mainly coronary heart disease) are the second leading killer disease category in Hong Kong since 1960s. About 12 persons per day died from the coronary heart disease in 2009. Thus, the long-term and efficient measurement of electrocardiography (ECG) for chronic heart disease patients is crucial and inevitable.
In the past two decades, polydimethylsiloxane (PDMS) has emerged as a typical biocompatible structural material for biomedical micro-devices. Indeed, applicability of PDMS can be extended to larger scale as an embedded material for the textile and clothing industries.
PDMS can be modified to be electrically conductive by addition of specific Nano-particles.
This highly controllable yet easily achievable modification process enables PDMS to become an interface material between traditional textile products and highly integrated electronic circuits.
This process potentially opens doors for industry of "intelligent clothes" - the functional wearable product that senses the human body’s characteristics.
