In covid pandemic, remote health monitoring has attracted tremendous attraction, however, the problem which we would like to address here that the sensors put on body to collect data need power which is given by rechargeable batteries and charging of battery interrupt health monitoring. Therefore, self powered sensors would be good alternative.

In general, the ordinary jackets can save the body up to a certain atmospheric temperature, either positive or negative temperature. Therefore, battery operated temperature controlled jackets are very useful. However, very few such type of jackets are available but as per our knowledge these available jackets are heavy in weight and also costly. Therefore, light weight and less expensive are needed to benefit most of peoples.

Power to remote health monitoring

Temperature controlled Jacket

Solution:

Body heat utilization in powering of wireless sensors in health monitoring using light weight flexible thermoelectric generators

Light weight flexible thermoelectric device to control temperature using external power supply (like battery). Thermoelectric based jackets can be used for both of cooling and heating purposes.
