1. MONITORING OF POSTURE ALLOCATIONS AND
ACTIVITIES BY A SHOE-BASED WEARABLE SENSOR
Abstract:
Monitoring of posture allocations and activities enables accurate estimation of energy
expenditure and may identify the problem in leg and providing further treatment . At present,
accurate devices rely on multiple sensors distributed on the body and thus may be too obtrusive
for everyday use. This paper presents a novel wearable sensor, which is capable of very accurate
recognition of common postures and activities. Using a bionic sensor, controller identifies the
problem in patient leg and wireless technology used to intimate condition of patient to remote
doctor.
Existing System:
In existing system patient only can feel the problem in leg, there is no provision to
identify patient problem. Doctor cannot identify directly seeing the patient. Hence we propose
the new system.
Proposed System:
In this project, we propose “monitoring of posture allocations and activities by a shoebased wearable sensor”. Here the bionic sensor are fixed in the shoe, the sensor output is
connected with embedded microprocessor. The PIC microcontroller is used to sense the bionic
sensor output. The PIC microcontroller having the internal Signal conditioning device and
microcontroller send the patient status to remote doctor using wireless technology. In this zigbee
wireless technology used to transfer the information to remote doctor. In receiver end
Microcontroller receives signal using zigbee transceiver and uploads to PC using RS232 serial
communication protocol and VB.NET application.
