The Household Fetal Doppler developed by Shenzhen Waveguider Optical Telecom Technology lnc is expected to stun visitors, especially expectant mothers, at this year's China Hi-Tech Fair.

The product lets pregnant women listen to their baby's heartbeat at home and keep an eye on the baby's condition.

It uses imported chips which make measured data more accurate. It also has a nano-silver coating which can resist bacteria and shield radiation to protect expectant mothers and their babies.

Small and light, the product is convenient to carry.
