Door­bells can test air qual­ity

The Sun (Malaysia) - - TECH TODAY -

AN IN­NO­VA­TIVE tech­nol­ogy that turns in­ex­pen­sive door bells or smoke alarm buzzers into air qual­ity mon­i­tors has re­ceived recog­ni­tion from Eng­land’s In­sti­tute of Physics (IOP).

The Tech­nol­ogy Part­ner­ship (TTP) was re­cently pre­sented with the IOP In­no­va­tion Award for its Son­icSense tech­nol­ogy.

TTP is a group of over 350 sci­en­tists, engi­neers and busi­ness in­no­va­tors with in-depth in­dus­try ex­per­tise, whose mis­sion is to turn great ideas into re­al­ity.

The Son­icSense tech­nol­ogy turns the piezo­elec­tric disk sen­sors used in door­bells or smoke alarms into highly ac­cu­rate, sta­ble and low power gas sen­sors, which the­o­ret­i­cally means any home can have a very sen­si­tive sen­sor to de­tect even low lev­els of gas con­tam­i­na­tion.

Piezo­elec­tric disks de­form un­der cer­tain forces and gen­er­ate an elec­tric pulse that trig­gers a beeper.

The tech­nol­ogy is al­ready in use by Philips Health­care in its oxy­gen con­cen­tra­tors, which are used by mil­lions of pa­tients stricken with res­pi­ra­tory dis­eases, but the TTP is work­ing with other part­ners to com­mer­cial­ize the tech­nol­ogy un­der a de­vel­op­ment and li­cens­ing agree­ment, and bring it to other ap­pli­ca­tions, such as en­ergy and in­dus­trial safety.

“The sen­sor is used to mon­i­tor the pu­rity of the oxy­gen con­cen­tra­tors’ gas out­put and trig­gers an alarm if the pu­rity is too low,” said Bob Mur­doch, di­rec­tor of Ad­vanced De­vel­op­ment for Philips Health­care.

“Son­icSense of­fers sev­eral ad­van­tages com­pared to cur­rent sen­sors in­clud­ing a long op­er­at­ing life, en­abling con­cen­tra­tors to run for tens’ of thou­sands of hours.

“Fur­ther­more, it doesn’t re­quire pe­ri­odic re-cal­i­bra­tion, which would be im­prac­ti­cal in pa­tients’ homes, and the low power-con­sump­tion en­ables con­cen­tra­tors to op­er­ate ef­fec­tively on bat­tery power.”

The IOP In­no­va­tion Awards are pre­sented an­nu­ally to busi­nesses that bring for­ward new physics­based prod­ucts, pro­cesses or ser­vices to mar­ket that im­prove prof­itabil­ity and jobs. – AFPRe­laxnews
